Subject Re: Hbase federated cluster for messages
Date Fri, 19 Aug 2016 18:57:30 GMT
As far as I know, HBase doesn't support spreading tables across namespaces;
you'd have to point it at one namenode at a time. I've heard of people
trying to run multiple HBase instances in order to get access to all their
HDFS data, but it doesn't tend to be much fun.
