      Description

      Release 0.18.0 removes the rpc timeout. So the namenode is ok to resolve a datanode's network location when the datanode registers. This could remove quite a lot of unnecessary code in both datanode and namenode to handle asynchronous network location resolution and avoid many potential bugs.
