Suresh Srinivas commented on HDFS-2140:
---------------------------------------
Comments:
# This might be a good opportunity to add some documentation to Host2NodesMap -
such as class javadoc.
# Also not sure why we call unprotectedAddDatanode? What is unprotected?
# Why is synchronization still dependent on namesystem.datanodeMap in
DatanodeManager#unprotectedAddDatanode()? We should have follow up items that
gets rid of unnecessary reference to namesystem in blockmanagement package.
> Move Host2NodesMap to block management
