    The code changes look fine to me.  My only concern is around HBase being able to support this.  My understanding was that the HBase RPC will cache the delegation token and will never go back to the UGI to get a new one once it is cached.  Have you tested this with HBase where the old delegation token has expired, a new one was fetched and pushed to the topology, and HBase needed to establish a new connection, not with the worker dieing but a connection to a new region server?

> This is a lot like STORM-346, but should have support for HBase instead of HDFS.
