> Components: nodemanager
> Affects Versions: 2.2.0
> Reporter: stanley shi
> Assignee: Masatake Iwasaki

> 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.
