-------------------------------
Attachment: D237.9.patch
Liyin updated the revision "[jira] [HBASE-4742] Split dead server's log in
parallel".
Reviewers: Kannan, khemani, Karthik, mbautin, JIRA
Refactor the code of RegionServerOperationQueue.
Each operation will return OPERATION.SUCCEEDED, OPERATION.FAILED and
OPERATON.DELAYED every time when it is processed.
Based on this return value, the RegionServerOperationQueue will put them back
to todo queue, delay queue or call the post-process-listener.

> When one region server goes down, the master will shutdown the region server
> and split its log.
> However, splitting log is a blocking call and it would take some time.
> If more than one region server go down, the master will split its log one by
> one, which is not efficient.
> Since we have the distributed log split, we could split these logs from the
> dead servers in parallel.
