Deprecated Interfaces

Interface and Description
org.apache.hadoop.hbase.coprocessor.CoprocessorService Since 2.0. Will be removed in 3.0
org.apache.hadoop.hbase.coprocessor.HasMasterServices Since 2.0.0 to be removed in 3.0.0. The hope is that by 3.0.0 we will not need this facility as CoreCoprocessors are integated into core.
org.apache.hadoop.hbase.coprocessor.HasRegionServerServices Since 2.0.0 to be removed in 3.0.0. The hope is that by 3.0.0 we will not need this facility as CoreCoprocessors are integated into core.
org.apache.hadoop.hbase.regionserver.RowProcessor As of release 2.0.0, this will be removed in HBase 3.0.0. For customization, use Coprocessors instead.
