[jira] [Commented] (HIVE-10050) Support overriding memory
configuration for AM launched for TempletonControllerJob
[ 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 ).
