Subject [jira] [Updated] (HADOOP-10950) rework heap management vars
Date Wed, 20 Aug 2014 14:36:26 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-10950?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Allen Wittenauer updated HADOOP-10950:

    Release Note: The default heap sizes have been removed.  This will allow for the JVM to
use auto-tuning based upon the memory size of the host.  To re-enable the old default, configure
HADOOP_HEAPSIZE_MAX="1g" in hadoop-env.sh.
