Java client exception

[ravi]

I get following exception when trying to connect to Java client
(I did copy the hbase-site.xml and put it in the classpath).
However, I can see the Master as running using the URL - http://hbase-docker:16010/master-status.
What am I missing? Any thoughts will be appreciated?
