Can you please check the regionserver log on datanode-001.fqdn.com that has 
hbase:meta region after enabling DEBUG log?
That will show the exact reason why the connections are failing.

Thank you Josh, that helps a lot.
We have Query Server on a dedicated server and none of existing guides have an information that we need to have core-site.xml with hadoop.security.authentication option set to kerberos.

Make sure you have authorization set up correctly between PQS and HBase.

Specifically, you must have the appropriate Hadoop proxyuser rules set
up in core-site.xml so that HBase will allow PQS to impersonate the PQS
end-user.
