Subject [jira] [Updated] (MAPREDUCE-5441) JobClient exit whenever RM issue Reboot command to 1st attempt App Master.
Date Wed, 28 Aug 2013 21:24:52 GMT

Vinod Kumar Vavilapalli updated MAPREDUCE-5441:
-----------------------------------------------

    Status: Open  (was: Patch Available)

The patch looks fine.

Please leave a comment as to why we are returning RUNNING.

Our code style is to use parenthesis all the time (changes in JobImpl).

We should also have a more direct test-case. You can use MRApp for this.
 - Start MRApp with a custom RMContainerAllocator.
 - Throw a token exception when MRApp heartbeats.
 - Check the end state by inspecting Job's state.
