MapReduce-Counting_Program

Anurag000-rgb/MapReduce-Repetation_Counting MapReduce Code for Counting the numbers in JAVA Basically in this project But it good to write in Apache Spark using scala Rather In Apache MapReduce

Both are Processing Framework on HADOOP and Implements Distributed Computation On Distributed Systems

Apache MapReduce =>

• faster than Apache Spark
• But Not Effecient
• It Implement Batch Processing

Apache Spark =>

• It Implements Batch Processing and Stream Processing
• It Works Effecient Than MapReduce

In Scala It Just One Line =>

Just Import Scala Context By SC

scala: sc.textFile('YOUR HDFS FILE LOCATION').map(input => input.split(" ")).flatmap(input => input).countByValue;
