@nij23  I have the correct account and resource role in my environment. I restarted the cluster created from the custom cluster definition and when I opened the CM-UI I got this message: Above Text for reference: HTTP ERROR 500 javax.servlet.ServletException: javax.servlet.ServletException: java.lang.NullPointerException: Custom client SSL context, if set, must not be null. URI: /test5/cdp-proxy/cmf/home/ STATUS: 500 MESSAGE: javax.servlet.ServletException: javax.servlet.ServletException: java.lang.NullPointerException: Custom client SSL context, if set, must not be null.

CAUSED BY: javax.servlet.ServletException: java.lang.NullPointerException: Custom client SSL context, if set, must not be null. CAUSED BY: java.lang.NullPointerException: Custom client SSL context, if set, must not be null.     When I try to open the CM-UI the second time and in any subsequent tries, I get the 403 Forbidden message. I see the 500 Servlet Exception only the first time when I try to access CM-UI.   Could it be because the "enableAutoTls" property was automatically set to false when I registered the custom cluster definition even though I had explicitly set it to true in my cluster definition JSON? ...

@nij23, Thanks. I created a cluster definition on CDP 7.2.6 (latest available version) following the above steps and was able to create a Data Hub with my custom CSD and parcels distributed, activated. I used the cdp cli to successfully create the datahub cluster.  I wanted to save this definition to use from the management console too, so I used "cdp datahub create-cluster-definition" command. But when I viewed the cluster definition JSON on Management console (Shared resources section), the "enableAutoTls" property was set to false even though I had set it to true explicitly in my JSON file. When I tried creating a cluster with this definition, I wasn't able to access the CM-UI or other service UIs after the cluster was created and in running state. Just wanted to point this out, that I am able to create cluster via cdpcli but via management console UI it was failing. Any suggestions on this? Additionally, Can you point me to any documentation for the model/schema of the CDP Cluster Definition? ... View more
