-----------------------------------
Summary: Support getting HBase tokens from multiple clusters and
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
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.
