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 :

}                           

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

Thanks.
