[jira] [Commented] (SPARK-6085) Increase default value for memory overhead

["Ted Yu (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SPARK-6085?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14342398#comment-14342398 ] 

Ted Yu commented on SPARK-6085:
-------------------------------

In my opinion, priority for this JIRA should be Major.

Users who deploy Spark on YARN in production are highly likely to hit computation failure(s). This would impact their business. Without intimate knowledge of Spark, it would take them some time to figure out the root cause.

> Increasing default value for memory overhead would improve out of box user experience.
