[jira] [Created] (YARN-1912) ResourceLocalizer started without any jvm memory control

stanley shi created YARN-1912:
---------------------------------

             Summary: ResourceLocalizer started without any jvm memory control
                 Key: YARN-1912
                 URL: https://issues.apache.org/jira/browse/YARN-1912
             Project: Hadoop YARN
          Issue Type: Bug
          Components: nodemanager
    Affects Versions: 2.2.0
            Reporter: stanley shi


In the LinuxContainerExecutor.java#startLocalizer, it does not specify any "-Xmx" configurations in the command, this caused the ResourceLocalizer to be started with default memory setting.
In an server-level hardware, it will use 25% of the system memory as the max heap size, this will cause memory issue in some cases.
