Subject [jira] [Commented] (MAPREDUCE-3068) Should set MALLOC_ARENA_MAX for all YARN daemons and AMs/Containers
Date Fri, 14 Oct 2011 21:06:11 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-3068?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13127858#comment-13127858

Arun C Murthy commented on MAPREDUCE-3068:
------------------------------------------

Yep, the putIfAbsent semantics are important since we want to allow containers to set an alternate
HADOOP_*_HOME. Does that make sense? Thanks.
