Jeff Zhang commented on TEZ-2249:
---------------------------------
[~bikassaha] Please help review. 2 new scenaio are added
* When task attempt succeeded, task should kill other task attempts and wait
for them to be killed before moving to SUCCEEDED.
* When failed task attempt count reach the limit, task should kill other task
attempts (we don't kill them now) and wait for them to be killed before moving
to SUCCEEDED.
> Wait for all task attempt finished before moving Task to finished state
