Cannot register a cluster, other causes
If you cannot register a cluster with DPS and none of the errors mentioned are the cause, the following might apply.
- Verify that the hostname where Knox is running is valid and reachable from the DPS host machine. If it is reachable, try adding the hostname resolution to the DPS container using the ./dpdeploy.sh utils add-host <ip> <host> command.
- Verify that network connectivity settings, such as firewalls, are correctly configured.
- Verify that the username is an Ambari Admin on the cluster. If not, make the user an Ambari Admin user, by logging into Ambari, selecting the user, and providing Admin privileges.
- See the Hortonworks Support Marix and verify that you are running a supported configuration.
