Class TestTableMapReduceBase

java.lang.Object
org.apache.hadoop.hbase.mapreduce.TestTableMapReduceBase
Direct Known Subclasses:
TestTableMapReduce, TestTableMapReduce
public abstract class TestTableMapReduceBase extends Object
A base class for a test Map/Reduce job over HBase tables. The map/reduce process we're testing on our tables is simple - take every row in the table, reverse the value of a particular cell, and write it back to the table. Implements common components between mapred and mapreduce implementations.
