> 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.
