Hyukjin Kwon resolved SPARK-16871.
----------------------------------
Resolution: Incomplete
> Support getting HBase tokens from multiple clusters dynamically
> ---------------------------------------------------------------
>
> Key: SPARK-16871
> URL: https://issues.apache.org/jira/browse/SPARK-16871
> Project: Spark
> Issue Type: Improvement
> Components: YARN
> Affects Versions: 2.0.0
> Reporter: Saisai Shao
> Priority: Minor
> Labels: bulk-closed
>
> 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.
