Package org.apache.hadoop.hbase.replication

Class TestMasterReplication.CoprocessorCounter

java.lang.Object

org.apache.hadoop.hbase.replication.TestMasterReplication.CoprocessorCounter

All Implemented Interfaces:

org.apache.hadoop.hbase.Coprocessor, org.apache.hadoop.hbase.coprocessor.RegionCoprocessor, org.apache.hadoop.hbase.coprocessor.RegionObserver

Enclosing class:

TestMasterReplication

public static class TestMasterReplication.CoprocessorCounter
extends Object
implements org.apache.hadoop.hbase.coprocessor.RegionCoprocessor, org.apache.hadoop.hbase.coprocessor.RegionObserver

Use a coprocessor to count puts and deletes. as KVs would be replicated back with the same timestamp there is otherwise no way to count them.
