@RajeshBodolla The general steps which I used to follow for Reinstall KTS from scratch this below, might be you are missing something.    1. Stop the KMS service 2. Delete the KMS service from the Cloudera Manager UI 3. Then remove all the contents under "rm -rf /var/lib/kms-keytrustee/" Note - Make sure that the hidden directory is also removed '/var/lib/kms-keytrustee/keytrustee/.keytrustee' 4. Now sync the Active and passive KTS using the following steps: a. Stop the Key Trustee Server service (Key Trustee Server service > Actions > Stop). b. Run the following command on the Active Key Trustee Server: $ sudo rsync -zav --exclude .ssl /var/lib/keytrustee/.keytrustee root@keytrustee02.example.com:/var/lib/keytrustee/. Note - Replace keytrustee02.example.com with the hostname of the Passive Key Trustee Server. c. Run the following command on the Passive Key Trustee Server: $ sudo ktadmin init d. Start the Key Trustee Server service (Key Trustee Server service > Actions > Start). e. Enable synchronous replication (Key Trustee Server service > Actions > Setup Enable Synchronous Replication in HA mode). f. Restart the Key Trustee Server service (Key Trustee Server service > Actions > Restart). Once this is done, now recreate the KMS service using the steps in the following link https://www.cloudera.com/documentation/enterprise/latest/topics/key_trustee_kms_ha.html ... View more

@Cl0ck You can always use OLD database, this is not am issue. For disabling TLS for admin console from CLI you can use below method.   1. Determine Cloudera Manager Database cat /etc/cloudera-scm-server/db.properties 2. Make database backup Postgres Backup: ---------------- pg_dump scm > scm_db_.backup 3. Connect to database Postgres Connect: ------------------ psql -U scm -h localhost -p 7432 -d postgres Password for user scm: postgres=> \l postgres=> \c scm 4. Show TLS related rows select * from CONFIGS where attr like '%tls%'; 5. Update TLS for web_tls update CONFIGS set value = 'false' where attr = 'web_tls'; You can generate the key and password as well with same method you did previously. Else please for reference you can use this doc.  https://docs.cloudera.com/documentation/enterprise/5-14-x/topics/how_to_configure_cm_tls.html ... View more

@dil4852  Yes, in CDH for many services History and Rollback option is available so for CDSW. Refer the screenshot. You can follow the below link for more details.  https://docs.cloudera.com/documentation/enterprise/6/6.3/topics/cm_mc_revert_configs.html    ... View more

@mon Cloudera Enterprise 6 requires Python 2.6 or higher on RHEL 6 compatible operating systems, but requires Python 2.7 or higher on RHEL 7 compatible operating systems. Only Hue and Spark2 needed Python 2.7 and rest of all CDH component in C6 train needs Python less than Python3. You can use Python 3 but not for CDH services until or unless you are trying some custom operations/job which needs some other Python version.    ... View more
