Hbase-mapreduce
WebAdd HBase and its dependencies (only) to the job configuration. This is intended as a low-level API, facilitating code reuse between this class and its mapred counterpart. It also of use to external tools that need to build a MapReduce job that interacts with HBase but want fine-grained control over the jars shipped to the cluster. WebA MapReduce is a data processing tool which is used to process the data parallelly in a distributed form. It was developed in 2004, on the basis of paper titled as "MapReduce: Simplified Data Processing on Large Clusters," published by Google. The MapReduce is a paradigm which has two phases, the mapper phase, and the reducer phase.
