---------------------------------
Thanks [~rakeshr] for the comments!

Alternate approach is to use FSNamesystem APIs directly like below.

I planed to use {{FSNamesystem.startFile()}} to create MOVER_ID_PATH, but it
have some issues here:
1) Extra work have to be done as in {{NameNodeRpcServer.create}} before call
{{FSNamesystem.startFile()}}, it duplicates the codes
2) It's also very hard for SPS to write hostname to mover id file as no API
provided.
