[jira] [Commented] (HIVE-12374) Improve setting of JVM configs for HS2 and Metastore shell scripts

    [ https://issues.apache.org/jira/browse/HIVE-12374?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15125545#comment-15125545 ] 

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.

> 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}}.
