we have found the issue with LLAP daemon port binding in LLAP app container logs. after killed the background llap java process we are able to start the hiveserverIntercative process sucessfully

Could you explain further please? I have the same problem.

When I restart HiveServer2 Interactive via Ambari, the later starts a yarn application named llap0 and still running a moment before it fails.

When I check via CLI :

hive --service llapstatus --name llap0

I get :

SLF4J: Class path contains multiple SLF4J bindings.

}

But on the Yarn Applications dashboard, the llap0 is in Running state (see attached picture).

Thanks.
