hiveserver2 and KILLJOB

[Stephen Sprague <sp...@gmail.com>]

hey guys,
this is a long shot but i'll ask anyway.   We're running YARN and
HiveServer2 (v2.1.0) and noticing "random" kills - what looks to me - being
issued by HiveServer2.

we've turned DEBUG log level on for the Application Master container and
see the following in the logs:

2016-10-05 02:06:18,365 DEBUG [IPC Server handler 0 on 34013]

job_1475268554936_14906 received from dwr (auth:SIMPLE) at 172.19.75.137


host 172.19.75.137 is where the HiveServer2 process is running.


i'm not seeing anything in the HiveServer2 logs at all that is related to
this job. that's whole 'nother problem.  also rerunning the M/R job works
fine.

so its very weird why out of the blue HS2 would issue a KILL.

this happens three or four times every day with random jobs.

Any thoughts greatly appreciated.

Cheers,
Stephen.
