[jira] [Resolved] (YARN-2481) YARN should allow defining the location of java

     [ https://issues.apache.org/jira/browse/YARN-2481?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Abin Shahab resolved YARN-2481.
-------------------------------
    Resolution: Cannot Reproduce
      Assignee: Abin Shahab

Verified on trunk that JAVA_HOME can be set for containers(mappers and reducers for example), and that is not overridden by the NM's JAVA_HOME.

> Yarn right now uses the location of the JAVA_HOME on the host to launch containers. This does not work with Docker containers which have their own filesystem namespace and OS. If the location of the Java binary of the container to be launched is configurable, yarn can launch containers that have java in a different location than the host.
