.@InterfaceAudience.Private @Deprecated public class GCMergedRegionsProcedure extends AbstractStateMachineTableProcedure<org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.GCMergedRegionsState>
This is a Table Procedure. We take a read lock on the Table. We do NOT keep a lock for the life of this procedure. The subprocedures take locks on the Regions they are purging.
