I have configured Hadoop-2.7.2 HA cluster in windows. Facing the below exception when starting second namenode NN2 with hdfs namenode -bootstrapStandby command

STARTUP_MSG: build = Unknown -r Unknown; compiled by 'Kumar' on 2016-01-2 8T06:05Z STARTUP_MSG: java = 1.7.0_51 ************************************************************/ 16/02/03 14:57:42 INFO namenode.NameNode: createNameNode [-bootstrapStandby] 16/02/03 14:57:43 FATAL ha.BootstrapStandby: Unable to fetch namespace information from active NN at nn1:9000: Unknown method isUpgradeFinalized called on org.apache.hadoop.hdfs.server.protocol.NamenodeProtocol protocol. at org.apache.hadoop.ipc.ProtobufRpcEngine$Server$ProtoBufRpcInvoker.call(ProtobufRpcEngine.java:604) at org.apache.hadoop.ipc.RPC$Server.call(RPC.java:969) at org.apache.hadoop.ipc.Server$Handler$1.run(Server.java:2049) at org.apache.hadoop.ipc.Server$Handler$1.run(Server.java:2045) at java.security.AccessController.doPrivileged(Native Method) at javax.security.auth.Subject.doAs(Subject.java:415) at org.apache.hadoop.security.UserGroupInformation.doAs(UserGroupInformation.java:1658) at org.apache.hadoop.ipc.Server$Handler.run(Server.java:2043) 16/02/03 14:57:43 INFO util.ExitUtil: Exiting with status 2 16/02/03 14:57:43 INFO namenode.NameNode: SHUTDOWN_MSG: /************************************************************ SHUTDOWN_MSG: Shutting down NameNode at nn2

I have verified my configurations. With the same configuration, HA cluster works fine with Hadoop-2.7.1

Do i have missed any new configuration? or Any special command for hadoop-2.7.2 added to form HA cluster?

Please help me in this.

I found the problem. Hadoop-2.7.2 refers old Tez jars which is built for hadoop-2.5.2. I have replaced Tez package and it works fine.

In Hadoop-2.7.1, it seems tez jars are not referred normally. But in Hadoop-2.7.2, Tez jars are referring and executing some methods from that.
