Alejandro Abdelnur commented on HDFS-4548:
------------------------------------------
If you have the following configuration set:
* keytab=<FILE>
* principal=<PRINCIPAL>
* useKeyTab=true
* useTicketCache=true
* renewTGT=true
then the JDK does the renewal for you. that is how hadoop-auth works on the
server side.
Back to UGI, UGI has a thread that triggers the relogin, why do we need to call
it explicitly?

> When the webhdfs SPNEGO token expires, the fs doesn't attempt to renegotiate
> a new SPNEGO token. This renders webhdfs unusable for daemons that are
> logged in via a keytab which would allow a new SPNEGO token to be generated.
