Bikas Saha commented on TEZ-1773:
---------------------------------

Attached patch rebased after TEZ-14.
1) added speculation error code handling
2) Renamed new enum to TaskAttemptTerminationCause to match existing 
Task/VertexTerminationCause
3) Added handling and tests for a few more error types

There are some TODOs to add test timeouts etc before commit. Please ignore 
them. [~zjffdu] Can you please take another look? Thanks!

> Add attempt failure cause enum to the attempt failed/killed history record
