> If LazyPersistFileScrubber.clearCorruptLazyPersistFiles throw an exception in run(),
there will be no sleep logic so it will restart immediately. However it may be still fail
so there are too many ERROR logs in namenode said "Ignoring exception in LazyPersistFileScrubber".
> We need sleep if we catch the exception.
