Haohui Mai commented on HDFS-8394:
----------------------------------
The v0 patch focuses on moving the code into a separate class. It tries to
minimize the changes.
The most notable change is in {{FSNamesystem#getAdditionalBlock()}}. It moves
the core implementation of the two parts of the functions to
{{FSDirWriteFileOp}} and keeps the safemode checks within the FSNameSystem.
> Move getAdditionalBlock() and related functionalities into a separate class
