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.master.procedure.MetaProcedureInterface only used for RecoverMetaProcedure. Should be removed along with RecoverMetaProcedure.
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.
org.apache.hadoop.hbase.coprocessor.SingletonCoprocessorService Since 2.0. Will be removed in 3.0

Deprecated Classes

Class and Description
