Suraj Menon updated HAMA-498:
-----------------------------
Status: Patch Available (was: Open)
The patch uploaded has few things to be considered:
- The test cases are passing most of the times. It still depends on scheduling
of certains threads.
- I still see killed tasks is runningTasks at Groomserver.
- LocalBSPRunner and the YARNRunner has been also changed with the new way of
handling errors in BSP jobs.
> BSPTask should periodically ping its parent.

> As described in http://wiki.apache.org/hama/GroomServerFaultTolerance
> BSPTask should periodically ping its parent 'GroomServer' for their health
> status.
> 1. If Tasks are unable to ping their parent 'GroomServer', it should be
> killed themselves.
> 2. And, if GroomServer does not receive ping from the childs, GroomServer
> should check whether that child is running.
> You don't need to implement recovery logic in this issue.
