Subject [jira] [Updated] (YARN-2129) Add scheduling priority to the WindowsSecureContainerExecutor
Date Fri, 06 Jun 2014 10:54:01 GMT

     [ https://issues.apache.org/jira/browse/YARN-2129?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Remus Rusanu updated YARN-2129:

    Attachment: YARN-2129.1.patch

Take 1. This implementation, leveraging the cmd.exe start [/LOW|/HIGH| /NORMAL] /WAIT /B command
line options, works fine except for the fact that, unlike *nix nice, the Windows processes
do *not* inherit the priority class except for lower priorites ([/LOW|/BELOWNORMAL]). Which
means that the cmd cotnainer script gets the priority boost, but not the actual java process
running the task. The localizer gets the priority boost proper, but that's does not really

I'll take a second stab at it and try to move the priority set to the actual java launch,
around ContainerLaunch.writeLaunchEnv() and ContainerLaunch.WindowsShellScriptBuilder et all.
