Subject [jira] [Updated] (YARN-1474) Make schedulers services
Date Thu, 16 Jan 2014 09:53:20 GMT

Tsuyoshi OZAWA updated YARN-1474:
---------------------------------

    Attachment: YARN-1474.4.patch

Thank you for the review, [~sandyr]! Updated a patch based on Sandy's comment. 

1. FairScheduler#serviceStop() now stops its threads.
2. Updated FairScheduler's test not to make it more readable(deleted type casts).

The cast Sandy pointed out is needed because ResourceScheduler interface has not the methods(FairScheduler#serviceStartInternal).

> Schedulers currently have a reinitialize but no start and stop.  Fitting them into the
YARN service model would make things more coherent.
