> Current HBase token obtaining mechanism is static, which can only get tokens from the clusters configured in hbase-site.xml and already added in classpath, this may possibly have several shortcomings for the long running services like Zeppelin and others:
> 1. User may want to access different HBase cluster in a secure way. but currently it can only support one.
> 2. User may want to change to another the cluster dynamically in the run-time. But current token obtaining mechanism can only support the one configured at the start.
> So here propose to improve the current token obtaining mechanism for HBase.
