---------------------------------------
[~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 daemons should try using YARN local dirs, if available

> 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).
