Matteo Bertozzi commented on HBASE-16056:
-----------------------------------------
no, this is a race condition. you should not be stuck there forever.
the other master should go down the after completing the operation,
or the one that is spinning will get aborted. we are spinning in a while
(isRunning())
> Procedure v2 - fix master crash for FileNotFound

> this may happen when the other master is still active (e.g. GC) and tries to
> remove files while the other master tries to become active. This operation is
> retryable so the code should able to handle that.
