Oleg Zhurakousky updated TEZ-1206:
----------------------------------
Attachment: TEZ-1206.patch.3.patch
Lighter patch addressing only essentials to fix these issues. Compatible with
the latest commit changes to DAGAppMaster
- Refactored DAGAPpMaster to simplify main(..) and improve lifecycle testing
- Eliminated dependency on System.exit while keeping it there just in case. In
time it could/should be removed
- Removed manual Thread creation in favor of ScheduledExecutorService
- Added Semaphore to control the lifecycle of DAGAppMaster
- Refactored services startup to aggregate all of the startup exceptions being
thrown instead of the first. Added ExceptionAggregator
- Added DAGAppMaster life-cycle test facilitating all possible stop conditions
ensuring it always stops naturally
