Ted Yu commented on HBASE-10000:
--------------------------------
bq. Why do reflection every time this method is called?
This is due to the change where the first call to recoverLease() gets moved to
SplitLogManager#splitLogDistributed().
In order not to abandon the on-going lease recovery for the WAL when
FSHDFSUtils#recoverDFSFileLease() is called, isFileClosed() is used.
> Initiate lease recovery for outstanding WAL files at the very beginning of
> recovery

> 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.
