Ok I got my setup working and I verified two things:
1) The tokens them self are not cached so if you call "obtainAndCacheToken"
it actually returns new tokens and adds it to the user object.
2) I looked at the code for both Hconnector implementation and I was able
to verify that they have an instance variable to store the user object and the
tokens from this user is only used during RPCClient's Connect phase. However
when I asked in hbase's user list if this will be an issue when token's expire
their response was no, because the only time authentication happens is when the
client connects. If the worker code has the same User object that is first
passed to instantiate Hconnector or Htable and keeps updating that user
object's subject with new delegation tokens as they arrive, things will work.
> (Security) Add AutoHDFS like credential fetching for HBase
