Hello,   There is no one Click solution in CDP to disable kerberos. As you pointed out, it is not recommended to disable kerberos once it's configured. Without kerberos, Ranger and other services might not work properly as Kerberos is the core security in CDP.   You can try to follow the below community post to check if that helps. https://community.cloudera.com/t5/Support-Questions/Disabling-Kerberos/m-p/19934#M38077 ...

Hi @Jessica_cisco,   The hbase:meta ( system table ) is not online and thus the Hbase Master has not come out of initialisation phase. We will need to assign the region for the hbase:meta table, as this table contains the mapping regarding which region is hosted on a specific Region server.
