public class OOMERegionServer extends org.apache.hadoop.hbase.regionserver.HRegionServer
A region server that will OOME. Everytime put(byte[], Put) is called, we add keep around a reference to the batch. Use this class to test OOME extremes. Needs to be started manually as in ${HBASE_HOME}/bin/hbase ./bin/hbase org.apache.hadoop.hbase.OOMERegionServer start.
