Hi @anis016 , In CDH5.16.2 we support this OpenJDK version: 1.8u181. Please use the tested version as documented in below doc: https://docs.cloudera.com/documentation/enterprise/release-notes/topics/rn_consolidated_pcm.html#concept_ihg_vf4_j1b I suggest you downgrade your OpenJDK version to lower and see if that will resolve the issue. Thanks, Li

Hi @kiranpune , Based on step 7 below, the answer is yes that you need to add the user in OS level. https://docs.cloudera.com/cloudera-manager/7.0.3/security-kerberos-authentication/topics/cm-security-kerberos-enabling-step7-prepare-cluster.html Here: Make sure all hosts in the cluster have a Linux user account with the same name as the first component of that user's principal name. For example, the Linux account joe should exist on every box if the user's principal name is joe@YOUR-REALM.COM. You can use LDAP for this step if it is available in your organization. Thanks, Li

@kiranpune , What is your CM version? Here is the latest documentation on Cloudera website. The step 3, 6 and 7 maybe the answer to your question. https://docs.cloudera.com/cloudera-manager/7.0.3/security-kerberos-authentication/topics/cm-security-kerberos-enabling-step6-user-principals.html Thanks, Li

Hi @pdev , You may want to check this community thread: https://community.cloudera.com/t5/Support-Questions/how-to-rollback-cloudera-manager-tls-configuration-without/m-p/46484 It is possible that some of the data was still in CM database which expects TLS login. Could you please run below SQL command to confirm? select attr, value from CONFIGS where attr in ('web_tls', 'agent_tls'); If you see any returned value is "true" then you need to update the CM database manually. See below steps: Back up database/table before you makde any further changes Run the following queries in the CM database: Update TLS for web_tls update CONFIGS set value = 'false' where attr = 'web_tls'; Update TLS for agent_tls update CONFIGS set value = 'false' where attr = 'agent_tls'; In the browser do clear cache including passwords, and cookies before trying to login. Thanks and hope this helps!
