[jira] [Resolved] (MAPREDUCE-31) Have a better shutdown and cleanup mechanism in JobTracker

["Harsh J (Resolved) (JIRA)" <ji...@apache.org>]

Harsh J resolved MAPREDUCE-31.
------------------------------

    Resolution: Not A Problem

This isn't a problem anymore on trunk. The JT has gone away and I do not think the MR2 components suffer from the same.

Besides, I've not seen this happen on branch-1 either, but I was not looking very close.

> The {{main()}} of JobTracker waits for {{offerSerice()}} to complete. {{offerService()}} does a {{Thread.join()}} on {{interTrackerServer}}. 
> {{JobTracker.close()}} stops {{interTrackerServer}} pretty early and hence there is a fair chance of JobTracker exiting before other threads are stopped _properly_.
