[jira] [Closed] (SPARK-16972) Move DriverEndpoint out of CoarseGrainedSchedulerBackend

["Reynold Xin (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/SPARK-16972?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Reynold Xin closed SPARK-16972.
-------------------------------
    Resolution: Won't Fix

Closing this as won't fix for now given the comments on the pull request. The risk of introducing a bug and making it more difficult to back port bug fixes outweighs the benefits in this case. If there is a stronger reason to do this (e.g. simplifies the development of new features), we can do this in the future.

> The CoarseGrainedSchedulerBackend class is too large and complex to understand or make improvements, because it contains an inner class DriverEndpoint and many members of CoarseGrainedSchedulerBackend are used in DriverEndpoint.
> So I am trying to move DriverEndpoint out of CoarseGrainedSchedulerBackend and make these two classes clean and easy to understand.
