Description
I was trying to abort a procedure which led to master shutdown.
Toward tail of the master log, I saw:
2016-08-29 20:25:26,180 ERROR [B.fifo.QRpcServer.handler=16,queue=1,port=20000] coprocessor.CoprocessorHost: The coprocessor org.apache.ranger.authorization.hbase.RangerAuthorizationCoprocessor threw java.lang.NullPointerException java.lang.NullPointerException at org.apache.hadoop.hbase.procedure2.ProcedureExecutor.isProcedureOwner(ProcedureExecutor.java:653) at org.apache.ranger.authorization.hbase.RangerAuthorizationCoprocessor.preAbortProcedure(RangerAuthorizationCoprocessor.java:835) at org.apache.ranger.authorization.hbase.RangerAuthorizationCoprocessor.preAbortProcedure(RangerAuthorizationCoprocessor.java:3107) at org.apache.hadoop.hbase.master.MasterCoprocessorHost$47.call(MasterCoprocessorHost.java:601) at org.apache.hadoop.hbase.master.MasterCoprocessorHost.execOperation(MasterCoprocessorHost.java:1146) at org.apache.hadoop.hbase.master.MasterCoprocessorHost.preAbortProcedure(MasterCoprocessorHost.java:597) at org.apache.hadoop.hbase.master.HMaster.abortProcedure(HMaster.java:2654) at org.apache.hadoop.hbase.master.MasterRpcServices.abortProcedure(MasterRpcServices.java:1070) at org.apache.hadoop.hbase.protobuf.generated.MasterProtos$MasterService$2.callBlockingMethod(MasterProtos.java:57274) at org.apache.hadoop.hbase.ipc.RpcServer.call(RpcServer.java:2127)
Under /procedures.jsp (after restart), the procedure I tried to abort had null as Owner.
