Hi Guys, I am trying to execute oozie workflow but facing below error:

[#1]

oozie job -oozie http://<Oozie_Server_Host>:11000/oozie/ -config cca.properties -submit Error: E0501 : E0501: Could not perform authorization operation, Operation category READ is not supported in state standby at org.apache.hadoop.hdfs.server.namenode.ha.StandbyState.checkOperation(StandbyState.java:87) at org.apache.hadoop.hdfs.server.namenode.NameNode$NameNodeHAContext.checkOperation(NameNode.java:1932) at org.apache.hadoop.hdfs.server.namenode.FSNamesystem.checkOperation(FSNamesystem.java:1313) at org.apache.hadoop.hdfs.server.namenode.FSNamesystem.getFileInfo(FSNamesystem.java:3928) at org.apache.hadoop.hdfs.server.namenode.NameNodeRpcServer.getFileInfo(NameNodeRpcServer.java:1109) at org.apache.hadoop.hdfs.protocolPB.ClientNamenodeProtocolServerSideTranslatorPB.getFileInfo(ClientNamenodeProtocolServerSideTranslatorPB.java:851) at org.apache.hadoop.hdfs.protocol.proto.ClientNamenodeProtocolProtos$ClientNamenodeProtocol$2.callBlockingMethod(ClientNamenodeProtocolProtos.java) at org.apache.hadoop.ipc.ProtobufRpcEngine$Server$ProtoBufRpcInvoker.call(ProtobufRpcEngine.java:616) at org.apache.hadoop.ipc.RPC$Server.call(RPC.java:969) at org.apache.hadoop.ipc.Server$Handler$1.run(Server.java:2206) at org.apache.hadoop.ipc.Server$Handler$1.run(Server.java:2202) at java.security.AccessController.doPrivileged(Native Method) at javax.security.auth.Subject.doAs(Subject.java:422) at org.apache.hadoop.security.UserGroupInformation.doAs(UserGroupInformation.java:1709) at org.apache.hadoop.ipc.Server$Handler.run(Server.java:2200)

Does any one has any idea that why we get such error ?

Hi @revan wabale,

Is the NN configured in HA? If yes, in your Oozie wf, you need to set the name node property to the name service of HDFS instead of one of the NN. This error probably means you point to one NN but this NN is not the active one anymore.

Hope this helps.

Thank You!
