Subject [jira] [Commented] (HDFS-2228) Move block and datanode code from FSNamesystem to BlockManager and DatanodeManager

-------------------------------------------

Hi Nicholas,
 Thanks for incorporating the comments.
 Latest changes looks good to me.
 +1 from my side.

5,6,7,8) You are correct that getAdditionalBlock(..), getAdditionalDatanode(..), abandonBlock(..),
allocateBlock(..) and datanodeReport(..) are supposed to be blockManager/DatanodeManager's
responsibility. However, as you mentioned, they require FSDirectory or other stuffs. So we
need to change the API before we can move them. Let's move them in separated JIRAs.

 Agree, lets raise separate JIRAs.

Can you check test results also with latest patch 
 ( fault  injection tests also :-) )


--Thanks
