Hello I am setting up multiple test environments composed of Hbase/OpenTSDB. Each test environment consists of 1 stand alone Hbase server and 1 to n OpenTSDB servers. The issue I am having is getting the Hbase region server to resolve to the IPv4 address on eth0, as opposed to 127.0.0.1. The OpenTSDB clients all think the region server they are looking for is at 127.0.0.1, when it is actually on another IP. Zookeeper on the stand alone Hbase server reports the region server in the meta table as 127.0.0.1 (at least this is how I interpreted the message). See log from OpenTSDB below:

However, neither seems to get Zookeeper to report the region server accurately though. I have restarted Hbase after changing each. The docs aren’t completely clear (at least to me) how Hbase determines what IP to put in Meta as the address for the region server. Would greatly appreciate some help understanding/clarification on how to get this set correctly. Thanks!
