Gavin updated HBASE-19040: -------------------------- Comment: was deleted (was: A comment with security level 'jira-users' was removed.) > CP service exec broken for older clients after PB namespace addition > -------------------------------------------------------------------- > > Key: HBASE-19040 > URL: https://issues.apache.org/jira/browse/HBASE-19040 > Project: HBase > Issue Type: Bug > Components: Coprocessors, Protobufs > Reporter: Josh Elser > Assignee: Josh Elser > Priority: Blocker > > Was investigating an upgrade failure at dayjob. The "old" version did not > include HBASE-14077 while the new version did include HBASE-14077. > After the servers have been upgraded, the clients which try to execute CP > calls will begin to fail with a message such as: > {noformat} > $ hbase(main):001:0> user_permission > User > Namespace,Table,Family,Qualifier:Permission > ERROR: org.apache.hadoop.hbase.exceptions.UnknownProtocolException: No > registered coprocessor service found for name AccessControlService in region > hbase:acl,,1508228211139.0ef76894681187f0ef958e78aed64d30. > at > org.apache.hadoop.hbase.regionserver.HRegion.execService(HRegion.java:7829) > at > org.apache.hadoop.hbase.regionserver.RSRpcServices.execServiceOnRegion(RSRpcServices.java:1980) > at > org.apache.hadoop.hbase.regionserver.RSRpcServices.execService(RSRpcServices.java:1962) > at > org.apache.hadoop.hbase.protobuf.generated.ClientProtos$ClientService$2.callBlockingMethod(ClientProtos.java:32389) > at org.apache.hadoop.hbase.ipc.RpcServer.call(RpcServer.java:2150) > at org.apache.hadoop.hbase.ipc.CallRunner.run(CallRunner.java:112) > at > org.apache.hadoop.hbase.ipc.RpcExecutor$Handler.run(RpcExecutor.java:187) > at > org.apache.hadoop.hbase.ipc.RpcExecutor$Handler.run(RpcExecutor.java:167) > {noformat} > The funny part is that the Region actually has a CP registered under the name > {{hbase.pb.AccessControlService}}, but the client asks for one under > {{AccessControlService}}. > I think the easy fix is to deploy the CP under both names while HBase > services support client backwards compatibility with 1.x clients. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
