Ashutosh Chauhan commented on HIVE-12374:
-----------------------------------------
Patch LGTM.
However, I think default Xmx value should be 8GB. 2GB looks too small for
daemon process for usual current hardware spec.
> Improve setting of JVM configs for HS2 and Metastore shell scripts

> Adding {{HIVESERVER2_JVM_OPTS}} and {{METASTORE_JVM_OPTS}} env variables,
> which will eventually set {{HADOOP_CLIENT_OPTS}} (since we start the
> processes using hadoop jar ...). Also setting these defaults:{{-Xms128m
> -Xmx2048m -XX:MaxPermSize=128m}}.
