datahub 2.3 vora-cluster validation failing. Invalid user

[pascaldp]

I have been trying to install datahub 2.3 on a local machine for learning purposes. I am documenting the setup in the following git. In short. Using vagrant I spun up a kubernetes cluster in a virtual environment consisting of a master and two nodes. I get all the pods running (except for vora-diagnostics that I don't install). However, the validation step fails. I have been skimming the different pod logs, but can't seem to find anything that I can relate to this issue.Any help or direction for further troubleshooting is appreciated?

No longer a problem. The problem was that the check-point store was not reachable.

During installation of datahub, you have to option to enable a checkpoint-store or not. The check-point store is needed to enable VORA tables of type streaming (these type of tables can be modified using UPDATE, INSERT, UPSERT, ...). It's stored outside the vora installation (e.g. in HDFS). If this is not reachable, the cluster-validation fails.

Despite of this, normally you should be able to login to the datahub application and start the vora tools. When I loged into "system" tenant with the "SYSTEM" user and password I provided during installation, I got a more elaborate error message.

Hello Pascal,

Can you please let me know what resolution steps you adopted ?
