Apache HBase

Last update: Jan 7, 2023

Overview

Apache HBase [1] is an open-source, distributed, versioned, column-oriented
store modeled after Google' Bigtable: A Distributed Storage System for
Structured Data by Chang et al.[2]  Just as Bigtable leverages the distributed
data storage provided by the Google File System, HBase provides Bigtable-like
capabilities on top of Apache Hadoop [3].

To get started using HBase, the full documentation for this release can be
found under the doc/ directory that accompanies this README.  Using a browser,
open the docs/index.html to view the project home page (or browse to [1]).
The hbase 'book' at http://hbase.apache.org/book.html has a 'quick start'
section and is where you should being your exploration of the hbase project.

The latest HBase can be downloaded from an Apache Mirror [4].

The source code can be found at [5]

The HBase issue tracker is at [6]

Apache HBase is made available under the Apache License, version 2.0 [7]

The HBase mailing lists and archives are listed here [8].

The HBase distribution includes cryptographic software. See the export control
notice here [9].

HBASE-26666 Add native TLS encryption support to RPC server/client
Originally was: HBASE-26666 Address bearer token being sent over wire before RPC encryption is enabled because it's needed for JWT authentication. The bearer token must be transmitted on an encrypted channel.

This code is partially based on ZooKeeper's Client TLS implmentation https://issues.apache.org/jira/browse/ZOOKEEPER-2120

https://issues.apache.org/jira/browse/HBASE-24506 is also affected, because I had to pass the entire eventLoopGroup to the Netty pipeline, otherwise SSL handshake has a race condition with Call submission

Still working on unit tests and documentation.

HBASE-26259 Fallback support to pure Java compression
This change introduces provided compression codecs to HBase as new Maven modules. Each module provides compression codec support without requiring new external dependencies. The codec implementations are shaded into the module artifacts.

Previously we relied entirely on Hadoop’s hadoop-common to provide compression support, which in turn relies on native code integration, which may or may not be available on a given hardware platform or in an operational environment. It would be good to have alternative codecs, provided in the HBase distribution, for users who for whatever reason cannot or do not wish to deploy the Hadoop native codecs. Therefore we introduce a few new options which offer a mix of pure Java and native accelerated options. Users can continue to use the Hadoop native codecs or choose what best meets their requirements of these new options.

  A JMH harness for measuring codec performance and microbenchmark results are attached to the JIRA. The test cases are realistic scenarios based on how we use compression in HFile.

 There is some future opportunity to optimize the block codec compatibility shims in the various modules. Output might not need to be unconditionally buffered. Buffer allocation time was included in the microbenchmark, could maybe pool and re-use buffers. Data movement into and out of buffers might be done with Unsafe. Follow up work. For the initial version we want an implementation known to operate correctly under all tested conditions.

hbase-compression: Parent module 

hbase-compression-aircompressor: Provides codecs for LZO, LZ4, Snappy, and ZStandard, using Aircompressor. These are all pure Java implementations. All except the ZStandard codec are data compatible with the Hadoop codecs. The ZStandard codec is limited by the algorithm implementation in Aircompressor, which is at an early stage and somewhat specific to Trino’s needs. These codecs, with the exception of ZStandard, offer reasonable performance relative to the Hadoop native codecs, for serving as alternatives. Performance is on par with the Hadoop codecs. Depending on parameters and codec the results might be +- 50% . This module is required to complete this work.

hbase-compression-lz4: Provides a codec for LZ4, using lz4-java. The codec is data compatible with and is faster than the Hadoop native codec. Up to 50% faster than Hadoop native. This is the fastest compression codec of all alternatives including the Hadoop native codecs. This module is optional but is very nice to have.

hbase-compression-snappy: Provides a codec for Snappy, using the Xerial wrapper. The codec is data compatible with the Hadoop native codec. The integration is different, that is the advantage here. Xerial provides native support bundled into the jar. It does not require deployment and management of separate native link libraries. It is slower than the Hadoop native Snappy codec by up to 75% but faster than most other algorithms regardless of implementation. This module is optional.

hbase-compression-xz: At my employer we have a private patch to Hadoop that provides a native codec for LZMA (XZ) and support for same in HBase. LZMA is an extremely aggressive and slow compression algorithm that is only suitable for certain specialized uses cases, but a pure Java option is provided by the algorithm’s developer as “XZ For Java”, so we can offer support for the LZMA algorithm now. This module is optional. 

The modular structure will enable us to offer additional alternatives at some future time, as desired.

HBASE-25869 WAL value compression
WAL storage can be expensive, especially if the cell values represented in the edits are large, consisting of blobs or significant lengths of text. Such WALs might need to be kept around for a fairly long time to satisfy replication constraints on a space limited (or space-contended) filesystem.

We have a custom dictionary compression scheme for cell metadata that is engaged when WAL compression is enabled in site configuration. This is fine for that application, where we can expect the universe of values and their lengths in the custom dictionaries to be constrained. For arbitrary cell values it is better to use one of the available compression codecs, which are suitable for arbitrary albeit compressible data.

SNAPPY or ZSTD at level 1 are recommended, all other options provided for comparison.

Microbenchmarks are collected with this change. Statistics are collected over the lifetime of the regionserver and are dumped at end of test at shutdown. Statistics are updated under synchronization but this is done in a way that excludes that overhead from measurement. The normal patch does not contain either the instrumentation or the synchronization point. Nanoseconds are converted to milliseconds for the table.

HBASE-26147: Add dry_run_balancer and related Admin interfaces for running the balancer without executing any region moves

See https://issues.apache.org/jira/browse/HBASE-26147

I considered adding another overload of the existing balance() methods, but I felt there already existed a lot of overloads there between the deprecated balancer() methods and the force boolean. Adding a separate dryRunBalance() method seemed like the cleanest and most intuitive way to add this new functionality in a backwards compatible way.

HBASE-22677 Add unit tests for org.apache.hadoop.hbase.util.ByteRangeUtils and Classes

I've analysed your codebase and noticed that org.apache.hadoop.hbase.util.ByteRangeUtils and Classes is not fully tested. I've written some tests for the methods in this class with the help of Diffblue Cover.

Hopefully, these tests will help you detect any regressions caused by future code changes. If you would find it useful to have additional tests written for this repository, I would be more than happy to look at other classes that you consider important in a subsequent PR.

HBASE-26807 Unify CallQueueTooBigException special pause with CallDroppedException

Creates a ServerOverloadedException as a base class for both exceptions. Creates a new configuration hbase.client.pause.server.overloaded and deprecates hbase.client.pause.cqtbe. Updates all references to "cqtbe" in code to "serverOverloaded", and changes instanceof checks to check for new base class ServerOverloadedException.

This patch mostly applies cleanly to branch-2, but I'm going to have to also re-implement it for the blocking client there. I will submit a PR for that once I get some initial agreement on the approach here.

HBASE-20598 - Upgrade to JRuby 9.2
After upgrade, prompt changed (mainly what it prints as session name, used to be "main" now the hbase object instance name). We decided to change prompt to"%N:%03n>", %N being Irb.conf[:IRB_NAME] (hbase) and %03n the line number.

Add to docs: For changelog please check https://www.jruby.org/news

Main changes: JRuby 9.2.0 minor release:

Ruby 2.5 language and stdlib support

225 issues fixed

JRuby versions up to 9.2.13.0 had various bugfixes, security fixes, performance improvements (memory reduction, runtime generations), IO improvements, basic support for java11,

Main gems changes:

9.2.11.0: Gems and gem paths packaged inside jar files will properly load now. This 9.2.10.0 regression was caused by a change in RubyGems 3 that exposed a bug in JRuby

9.2.10.0: RubyGems has been updated to version 3.0.6.

HBASE-26347 Support detect and exclude slow DNs in fan-out of WAL

This issue provides the method to detect slow datanodes by checking the packets processing time of each datanode connected by the WAL. When a datanode is considered slow, the datanode will be added to an exclude cache on the regionserver, and every stream created will exclude all the cached slow datanodes in a configured period. The exclude logic cooperate with the log rolling logic, will react more sensitively to the lower slow datanodes, whatever there is hardware failure or hotspots. On our production cluster with 20% machines with hardware failure, the RS serves stably and can keep a high availability. Without this feature on the same cluster, there is frequently aborting of RSes, which caused by wal stuck when flushing cache.

HBASE-22618 Provide a way to have Heterogeneous deployment

Hi!

This is the PR regarding HBASE-22618. The goal of the PR is to allow Heterogeneous HBase clusters.

We would like to allow users to load custom cost functions that can implement newer ways of balance regions.

This first commit is providing to possibility load them, and a second commit on this branch will add an working example of a custom cost function. This custom function will allow users to balance regions according to an allowed number of regions per RS.

Before implementing the cost function, I want to validate first the dynamic load :smiley:

HBASE-27227 Long running heavily filtered scans hold up too many ByteBuffAllocator buffers

I still need to add unit tests, but this works in a deployed cluster. Submitting early in case anyone wants to comment on the approach.

The basic premise is that currently we only call Shipper.shipped() at the final stage of returning an RPC. This was considered the only place where it was safe to release the blocks, which is true for result-referenced blocks. If we can be sure that a block is not referenced by any returned cells, we should be able to release them early. Shipper will still do the final release of anything retained in prevBlocks.

RegionScannerImpl and StoreScanner both scan rows at a time and enforce different levels of filters. StoreScanner enforces most of the per-cell filters with a hot loop over cells in the row for that store. At this level we can simply release the block if no cells are matched with qcode INCLUDE*. We do this by calling heap.retainBlock() when including a result, which sets a boolean in HFileReaderImpl. When HFileReaderImpl progresses to the next block, it will only add the old block to prevBlocks if retainBlock() had been called. Otherwise it releases it at that point.

The RegionScannerImpl level enforces filterRow() filters, since it has the full set of cells for the row. If the row is deemed filtered, the results list is cleared. We handle this level by adding a checkpoint system. At the start of a RegionScannerImpl.next call, checkpoint(START) is called. This sets an index in HFileReaderImpl based on the current size of prevBlocks. Once RegionScannerImpl has decided to filter a row, we call checkpoint(FILTERED) which releases any blocks that had been added to prevBlocks in the creation of cleared result list.

In order to ensure these don't have adverse affects on unexpected use-cases of HFileReaderImpl, the new behavior is only triggered once checkpoint(State) is called on a scanner. Prior to calling checkpoint, the old behavior will remain in place where all old blocks are added to prevBlocks and only released by calling shipped().
