Subject [jira] [Updated] (MAPREDUCE-3068) Should set MALLOC_ARENA_MAX for all YARN daemons and AMs/Containers
Date Fri, 07 Oct 2011 12:25:30 GMT

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

Vinod Kumar Vavilapalli updated MAPREDUCE-3068:
-----------------------------------------------

    Status: Open  (was: Patch Available)

Thanks for taking this up!

Gone through the patch, some comments:
 - Now that the configuration is getting added for NM white-list of envs, I think we can close
MAPREDUCE-2748 as duplicate and use this same configuration for passing HADOOP_CONF_DIR, JAVA_HOME,
HADOOP_COMMON_HOME, HADOOP_HDFS_HOME, YARN_HOME to the containers. The defaults can still
fall back to the values from NM Env. What do you think?
 - Need to add the new configuration to yarn-default.xml
 - Also, helps to have a couple of tests for this to verify that the configured values for
the NM are getting passed to the containers.
