I made a change on my hdfs advanced config using the Ambari webui and then wanted to go back to a previous state using the saved configuration. After doing that, something broke. Ambari will not load the config menu anymore, I just get a spinning icon.
I checked the ambari-server log and this is what comes up:
Error Processing URI: /api/v1/clusters/clustername/configurations/service_config_versions - (java.lang.NullPointerException) null
I attempted performing a service restart for ambari-server on the name node but that didn't help the situation.
How can I manually revert the config version?
I'm using Ambari 2.5.2 with HDP 2.6.2
