[jira] [Commented] (OOZIE-2073) Make max limit of memory setting in uber mode configurable

    [ https://issues.apache.org/jira/browse/OOZIE-2073?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14225248#comment-14225248 ] 

Rohini Palaniswamy commented on OOZIE-2073:
-------------------------------------------

Issue was with non-heap space. 3.5G Heap and 512MB non-heap is good for 99% of the jobs. Also with jdk8 more heap memory is used than native memory. I think we should leave it at what is there now and make folks configure lesser memory if a job fails.

> in uber mode, we apply heap size limit of 3584m for 32 bit case, which is hardcoded. but OOM happened in some use case.   we can make it configurable  and reduce default value to 3328m (3.25G) based on hadoop folk's suggestion.
