Subject [jira] [Updated] (YARN-2328) FairScheduler: Verify update and continuous scheduling threads are stopped when the scheduler is stopped
Date Thu, 24 Jul 2014 22:31:39 GMT

     [ https://issues.apache.org/jira/browse/YARN-2328?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Karthik Kambatla updated YARN-2328:
-----------------------------------

    Attachment: yarn-2328-preview.patch

Here is a preview patch that introduces FSBackgroundTasksRunner. As of now, only UpdateThread
and ContinuousSchedulingThread are added here. We might want to move the AllocationFileLoaderService
also here. 

Appreciate any initial feedback on the approach or the patch.

> FairScheduler threads can use a little cleanup and tests. To begin with, the update and
continuous-scheduling threads should extend Thread and handle being interrupted. We should
have tests for starting and stopping them as well.
