> Kylin uses HBase as the metastore; But in some cases user expects the metadata not in
HBase.
> Sonny Heer from mailing list mentioned:
> "I'm fairly certain anyone using Kylin with AWS EMR will benefit from this.   Having
multiple hbase clusters across AZs is a huge benefit.  BTW only thing blocking at the moment
is write operations happening from kylin query nodes."
