Lefty Leverenz commented on HIVE-8452:
--------------------------------------
Doc note: This adds configuration parameter *hive.tez.cpu.vcores* to
HiveConf.java, so it needs to be documented in the wiki. A release note would
also be nice.

> Currently there's a way to configure container size for tez as well as java
> opts to start containers.
> However, if you only set container size and not java opts, we fall back to MR
> settings for java opts which will likely fail (killed by yarn).
> vcores is always taken from the MR settings. Need to have a way to overwrite
> that too.
> Tez 0.5 and onwards will automatically generate the right java opts string
> when the container/cpus are specified. This is preferable to falling back to
> MR.
