Not able to approve datalab – Viewpoint


Cannot approve any new Datalabs request as well as cannot add any user to a datalab.

Your request has failed. The supplied string array has null, empty, or blank (all whitespace) elements, or is null or empty itself.
You may also see any Datalab approval just hanging and not completing or throwing any error.

When you look at viepoint log file located at /opt/teradata/viewpoint/portal/logs/viewpoint.log you will see errors like below:

2015-10-11 11:11:50,596 ERROR [http-nio-9080-exec-4] {context=/DataLabsPortlet, user=admin} impl.JaxbMessageSender.getHostName(336) – Could not get host name.
Just add the hostname to the host file (/etc/hosts) to resolve the issue: localhost ViewPointServername_VP
You will probably see this issue after upgrading to viewpoint version
