> Handle empty rename pending metadata file during atomic rename in redo path
> During atomic rename we create metadata file for rename(-renamePending.json).
> We create that in 2 steps
> 1. We create an empty blob corresponding to the .json file in its real
> location
> 2. We create a scratch file to which we write the contents of the rename
> pending which is then copied over into the blob described in 1
> If process crash occurs after step 1 and before step 2 is complete - we will
> be left with a zero size blob corresponding to the pending rename metadata
> file.
> This kind of scenario can happen in the /hbase/.tmp folder because it is
> considered a candidate folder for atomic rename. Now when HMaster starts up
> it executes listStatus on the .tmp folder to clean up pending data. At this
> stage due to the lazy pending rename complete process we look for these json
> files. On seeing an empty file the process simply throws a fatal exception
> assuming something went wrong.
