[jira] [Commented] (TEZ-699) Have sensible defaults for java opts

    [ https://issues.apache.org/jira/browse/TEZ-699?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14045066#comment-14045066 ] 

Hitesh Shah commented on TEZ-699:
---------------------------------

The only gotcha that I will call out is that the code only checks for Xmx and not Xms. If only Xms is set, the framework will override it in favor of the computed settings.

> Its a burden to have to specify them all the time. API's already exist if users want to set special values. Also, for vertex memory would be good to have a TezUtils.getDefaultVertexResource() with a sensible resource size.
