Jitendra Nath Pandey commented on HADOOP-7510:
----------------------------------------------
Please remove the rack related change in MiniDFSCluster. That doesn't seem
necessary. It will be surprising if some tests break without that change, and
might indicate some other bug.
Patch looks good to me otherwise.

> Tokens currently store the ip:port of the remote server. This precludes
> tokens from being used after a host's ip is changed. Tokens should store the
> hostname used to make the RPC connection. This will enable new processes to
> use their existing tokens.
