> reloginFromKeytab() should happen even if TGT can't be found

> HADOOP-6965 introduced a getTGT() method and prevents reloginFromKeytab()
> from happening when TGT is not found. This results in the RPC layer not being
> able to refresh TGT after TGT expires. The reason is RPC layer only does
> relogin when the expired TGT is used and an exception is thrown. However,
> when that happens, the expired TGT will be removed from Subject. Therefore,
> getTGT() will return null and relogin will not be performed. We observed, for
> example, JT will not be able to re-connect to NN after TGT expires.
