Description
NameNode automatically starts a LazyPersistFileScrubber thread to remove missing block files from namespace.
However, for testing/dev purposes, if I simply want to load a NameNode with a fsimage, the thread would still kick off and consume CPU resources. That's quite annoying.
I would like to propose an option to disable this thread if a developer knows exact what he/she is doing.
