"hbaseTable" cannot read from HBase about spark-hbase-connector

Looks from your logs that you cannot connect to machine 10.14.116.11:60020 or that the DNS server returns the wrong address for server1.dev.hbaseserver.com. I've seen some cluster configurations making a lot of confusion between public and LAN IPs. Make sure 10.14.116.11 is the internal IP (usually without firewall rules) and not the external one.

You should also look at the configuration to check if a region server is started in that machine, that it listens on port 60020 and that every machine of the cluster (master included) can telnet to that host:port pair.

Note that port mapping has changed in HBase 1.1+. So if region servers are listening on a different port there could be something wrong with the connector.

@nicolaferraro Thank you for your reply.
The 10.14.116.11 is the internal IP, firewall has been disabled.
Hbase version is 1.0.0, and we use all default settings.
I am checking with our cluster admin with your suggestion. I will update this post if any improvement.
One thing I forgot to mention is that we enabled Kerbros security, could that caused the issue?
