YARN resourcemanager error

[#1]

Hi,

Can someone please help me resolve this error below when accessing the resourcemanager UI?

Incompatible versions found, clientVersion=0.7.0.2.6.1.0-129, AMVersion=0.8.4.2.6.1.0-129

Session stats:submittedDAGs=0, successfulDAGs=0, failedDAGs=0, killedDAGs=0

Thanks,

@ryu You might hitting the same issue reported on this thread.

Apply the solution and see if that helps.

Thanks @GangWar for the response. What if we do not have Oozie installed in the cluster?

Would I still be able to run the commands in the link?

@ryu I don't think so those are oozie commands.
