Krishna Ramachandran commented on MAPREDUCE-1778:
-------------------------------------------------

"if its writable and readable"

I have NO knowledge of any API that will check for this (other than creating a dummy file)
Look at JobHistory - what i have done is similar. 

Chris, 
Can you comment?

I fixed the line alignment per hadoop formatter 

As for test case, I let me check and if relevant use the existing test

> If {mapred.job.tracker.persist.jobstatus.dir} points to an unwritable location or mkdir of {mapred.job.tracker.persist.jobstatus.dir} fails, then CompletedJobStatusStore silently ignores the failure and disables CompletedJobStatusStore. Ideally the JobTracker should bail out early indicating a misconfiguration.
