Subject [jira] [Updated] (MAPREDUCE-3068) Should set MALLOC_ARENA_MAX for all YARN daemons and AMs/Containers
Date Fri, 14 Oct 2011 07:02:12 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-3068?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Arun C Murthy updated MAPREDUCE-3068:
-------------------------------------

    Status: Open  (was: Patch Available)

Chris - this looks great, thanks for the nice refactor to use it in both NM and MR apps.

One nit is that we want the 'putIfAbsent' semantics i.e. allow containers to override HADOOP_*_HOME
etc. Could you please fix it? 

Also, can you please look at the javadoc warnings? 

Thanks!
