Subject [jira] [Commented] (HIVE-14392) llap daemons should try using YARN local dirs, if available
Date Mon, 01 Aug 2016 22:06:20 GMT

Siddharth Seth commented on HIVE-14392:
---------------------------------------

[~leftylev] - thanks for the detailed look at the description. Will incorporate most of that
in the next patch.

bq. Why did we make it required in the first place? I remember there was an explicit reason,
I just don't remember what it was. We were always running on YARN only, too
LLAP started with running without Slider - i.e. setup daemons manually on individual nodes
(outside of YARN). At that point the work.dir configuration was required. I think we just
never really needed to change the way it was used, so this did not get attention.

> LLAP required hive.llap.daemon.work.dirs to be specified. When running as a YARN app
- this can use the local dirs for the container - removing the requirement to setup this parameter
(for secure and non-secure clusters).
