Question
Java is mandatory to write mapreduce jobs?
Answers
No, By default Hadoop implemented in JavaTM, but MapReduce applications need not be written in Java. Hadoop support Python, Ruby, C++ and other Programming languages. Hadoop Streaming API allows to create and run Map/Reduce jobs with any executable or script as the mapper and/or the reducer.Hadoop Pipes allows programmers to implement MapReduce applications by using C++ programs.   Your Comment
