lyc updated SPARK-20869:
------------------------
Description:
In `Master.removeWorker`, master clears executor and driver state, but does not
clear app state. App state is cleared when received `UnregisterApplication` and
when `onDisconnect`, the first is when driver shutdown gracefully, the second
is called when `netty`'s `channelInActive` is called (which is called when
channel is closed), both of which can not handle the case when there is a
network partition between master and worker.
Follow the steps in
[SPARK-19900|https://issues.apache.org/jira/browse/SPARK-19900], and see the
[screenshots|https://cloud.githubusercontent.com/assets/2576762/26398697/d50735a4-40ac-11e7-80d8-6e9e1cf0b62f.png]
when worker1 partitions with master, the app `app-xxx-000` is still running
instead of finished because of worker1 is down.
