[jira] [Updated] (YARN-2399) FairScheduler: Merge AppSchedulable and FSSchedulerApp into FSAppAttempt

     [ https://issues.apache.org/jira/browse/YARN-2399?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Karthik Kambatla updated YARN-2399:
-----------------------------------

    Attachment: yarn-2399-1.patch

Here is a patch that merges the two. I have kept most of the code as is, and made minor improvements at places that change one to the other. 

Verified locally that the tests pass. Given this is a huge change, I would like to get this in ASAP and fix up any minor issues/concerns in follow-up patches.

> FairScheduler has two data structures for an application, making the code hard to track. We should merge these for better maintainability in the long-term.
