Hi Community,   We are working on a new requirement where I need to disable table-level TTL and rather use cell-level TTL for one of our HBase tables.   I can disable the table-level TTL by altering the table property and set cell-level TTL for new incoming data. However, I can't find anything on how can I set cell-level TTL for the data / rows that are already existing in the table.   Any suggestions will be very helpful.   Thank you, Snehasish ...

Hello Community, I want to decommission an entire cluster, so I went looking around for any documentation that mentions any recommended procedure to follow but couldn't find any.  Hence, i turned towards the community, if anyone here have decommissioned a kerberized and sentry-enabled cluster and can advice me on any best practices I can follow. I think it is worth mentioning that our cluster is created using Cloudera Altus Director.   Thank you, Snehasish ... View more

Hello Community, I have a CDH 5.14 cluster hosted on EC2 machines which is kerberized with Active Directory and have Sentry for authorization of databases.  I want to use SSSD to secure my Linux hosts (RHEL 7.x) with Active Directory.  I have been going through this post but there are few queries which are bothering me to proceed forwards: 1. There are service-users (Hive, YARN, etc.) in AD that are already created during Kerberization of my cluster. So, if I go ahead and implement SSSD, then will these pre-existing service-users be able to communicate? 2. If something goes wrong will I be able to rollback? If yes, how?   ... View more

Scenario: I recently integrated Altus Director with Active Directory for role based authentication & authorisation. After implementation I noticed that the default admin credential (admin/admin) was not working anymore, which was expected.   My question is: Is it possible/recommended to create another 'admin' user in Altus director (or in Active Directory) as a master credential just for back-up? Do Altus Director have a Authentication Backend Order (eg. Database then External) like we have in Cloudera Manager? Suppose, if a user is present in admin group as well as readonly group, then what role does Altus Director assumes for that user? Thank you. ... View more
