Yeah, it likely means that your HBase configuration is in interact for using the remote cluster. When you run the Flume agent, can you do a `ps aux | grey flume` and find where the hbase-site.xml is coming from? It's probably /etc/hbase/conf. Look in the file, and can you tell me what the value of the zookeeper quorum parameter is?
