Jeff Zhang commented on TEZ-2204:
---------------------------------
Upload patch. [~hitesh] [~bikassaha] Please help review it.
2 potential dead lock:
* Related to YARN-2917. Tez's AsyncDispatcher doesn't integrate its patch.
* Deadlock in DAGAppMaster. method DAGAppMaster::handle &
DAGAppMaster:stopService. While stopService is called, it would stop the
AsyncDispatcher, while AsyncDispatcher will drain its events which may call
DAGAppMaster::handle. And method handle() & stopService both has the
synchronized keyword.
> TestAMRecovery increasingly flaky on jenkins builds.
