Subject [jira] [Commented] (HADOOP-7510) Tokens should use original hostname provided instead of ip

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

> Fixed hftp/hsftp to return the correct uri with the correct port, but return a canonical
service with the 
> secure port (which strays from other filesystems).
  What problems you ran into that compelled to use https port for service in hftp file system?
Earlier and for hdfs it uses rpc port. Rpc port is used, because eventually its the Rpc port
that is passed in TokenSelector to select a token (from ipc.Client). Was it tested with secure
hftp setup or is there a different call flow that I am missing?

> Modified the getCanonicalService changes to be compatible with expectations of the TokenCache.
 This method returns null for all the file systems that don't have a valid authority. Why
is this change required? This is a public API, I am uncomfortable modifying it to return null
for all file systems except hdfs, hftp. TokenCache should work fine if a string is returned,
it has been working fine with strings so far.

> 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.
