Subject [jira] [Commented] (YARN-1912) ResourceLocalizer started without any jvm memory control
Date Tue, 08 Apr 2014 14:08:16 GMT

    [ https://issues.apache.org/jira/browse/YARN-1912?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13963010#comment-13963010
] 

Nathan Roberts commented on YARN-1912:
--------------------------------------

Doesn't it default to MIN(25%_of_memory,1GB)? May not be too bad on modern server class machines,
but probably best to explicitly call out a maximum.

> 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.
