LLAP HiveServer decode error

[dan young <da...@gmail.com>]

Hello All,

Still trying to get this LLAP working, and from what I can tell, it seems
to be working except whenever I try to navigate to the HiveServer Web
UI->LLap Daemons.  The UI lists them as "Launching" (screenshot 1). This
impacts when I have the hive.execution.mode=llap of course....

When I go into zookeeper and get check the nodes, I can see the LLAP worker
information, and I can even navigate to the WEB UI of the LLAP daemon
(screenshot 2a and b)

I noticed that the following entry in the HiveServer log when I do try to
navigate to the LLAP Daemons tab

 impl.ZkRegistryBase: Unable to decode data for zkpath:
/user-hadoop/looker-llap/workers/worker-0000000000. Ignoring from current
instances list..


I noticed the zkpath list doesn't match the
/llap-unsecure/user-hadoop/looker-llap/workers/worker-0000000000 path when
looking in zookeeper.  Do these need to match?  It seems that HiveServer is
looking for a path that doesn't exist.... what configuration
variable/hive-site.xml setting can I set to fix this?

Any ideas?????

Dano
