Subject [jira] [Commented] (HIVE-10050) Support overriding memory configuration for AM launched for TempletonControllerJob
Date Wed, 01 Apr 2015 05:44:53 GMT

    [ https://issues.apache.org/jira/browse/HIVE-10050?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14390018#comment-14390018

Lefty Leverenz commented on HIVE-10050:
---------------------------------------

Doc note:  This adds *templeton.controller.mr.am.java.opts* and *templeton.mr.am.memory.mb*
to webhcat-default.xml, so they need to be documented (with version information) in the WebHCat
Configuration wikidoc.

> The MR AM launched for the TempletonControllerJob does not do any heavy lifting and therefore
can be configured to use a small memory footprint ( as compared to potentially using the default
footprint for most MR jobs on a cluster ).
