Package org.apache.hadoop.hbase.regionserver

Class NoOpScanPolicyObserver

java.lang.Object
org.apache.hadoop.hbase.regionserver.NoOpScanPolicyObserver
All Implemented Interfaces:
org.apache.hadoop.hbase.Coprocessor, org.apache.hadoop.hbase.coprocessor.RegionCoprocessor, org.apache.hadoop.hbase.coprocessor.RegionObserver
public class NoOpScanPolicyObserver extends Object implements org.apache.hadoop.hbase.coprocessor.RegionCoprocessor, org.apache.hadoop.hbase.coprocessor.RegionObserver
RegionObserver that just reimplements the default behavior, in order to validate that all the necessary APIs for this are public This observer is also used in TestFromClientSideWithCoprocessor and TestCompactionWithCoprocessor to make sure that a wide range of functionality still behaves as expected.
