Himanshu Vashishtha commented on HBASE-10000:
---------------------------------------------

> At the beginning of recovery, master can send lease recovery requests concurrently for
outstanding WAL files using a thread pool.
> Each split worker would first check whether the WAL file it processes is closed.
> Thanks to Nicolas Liochon and Jeffery discussion with whom gave rise to this idea.
