Hi @arunek95 I went through the docs. Wasnt able to find minimum RAM for the nodes. If I were to create to create 3 VMs for nodes, will 4GB be enough? Also, will 8GB be bare sufficient for the main Cloudera manager node? Asking this, as I will be using VMware workstation 15.5 on Windows 10 Pro. Need to get the memory correct for the cluster machines. Thanking you. Warm Regards, Plascio

Hi@ arunek95,yes. But you gave me the idea. After I deleted the alert_current and alert_history tables data, the problem was solved. I don't know why, you know? And thank you very much PREVIEW

Hello @dhughes20 , I can see when we navigate to a Hive table in Atlas UI we have an audit tab. I tried to update the table by adding a new column. After altering the table I can see the audit is showing actions for "Entity update" and when we expand the latest entry we were able to see details like last modified time , last modified by and more details under "Parameter". But I am not able to find any audit log which shows what changes were made.

Hi @drgenious , We have this doc which explains the steps to migrate Oozie WF's from CDH to CDP , please have a look on it. https://docs.cloudera.com/cdp-one/saas/cdp-one-data-migration/topics/cdp-saas-oozie-migration-workflows-in-cdh.html If you still have more queries please reach out to our support through Cloudera portal.

Hi @KPG1 , As per the description I believe you are looking for a way to have a high availability for HMS , if that is the case please find the below doc which can help - https://docs.cloudera.com/cdp-private-cloud-upgrade/latest/upgrade-cdh/topics/hive-hms-ha-configuration.html And for the backend DB to configure it for HA , it will be out of scope of Cloudera and you have to work with DB team itself to understand how they can configure.

Hi Kamal, You're replying to a ticket from over a year ago. I would suggest creating a new ticket and providing some more details on what exactly you're seeing. Did you follow the suggestions in the previous replies and if so what was the outcome? Cheers, Jim

Hi @hebamahmoud , can you please check the details of the failed operation. Also check the agent logs or the CM server logs to see if any relevant error related to this issue. You can tail the logs and retry the same operation to check the live logs.

arunek95 · ‎07-06-2022

Hi @pshah566 , Do you see anything in the cm server logs. Please check that and see if it is reporting any error or warning that can help us here.

arunek95 · ‎07-06-2022

Hi @KingMax , From the description I can understand that when you are adding host_components (KERBEROS_CLIENT, DATANODE) via AMBARI rest api it is ABORTING and not creating any keytabs and later you have to manually regenerate it. Please correct me if I am wrong. If you are not seeing any error in the logs , please check the browser network tab to see what is happening with the API and the operation.

Hi @massa , From the error I can interpret it can be an issue with the CM repo. Try copying the repo file from the working host to the non working and see how it goes.

The Hbase Masters can be stuck on a Standby state if it is still recovering the lease on the MasterprocWALs. You can check the same by looking at the restart logs of the Hbase Masters. Check: hdfs dfs -ls -R /apps/hbase/data/MasterProcWALs > Check How Many Files (10000) Possible Solution: Sideline MasterProcWALs + Waiting On RecoverLease

Hi @novice_tester , You can look for Backup -> replication schedules in the CM UI. Sharing the doc for reference - https://docs.cloudera.com/documentation/enterprise/5-13-x/topics/cm_bdr_about.html Let me know if it helps.

Hi Navanil, Can you please try to check the Ambari server logs and see what error or warn is reported in it. Are you using admin/admin credentials ? If not can you please try that. Also check the ambari.properties have the right server hostname.

arunek95 · ‎12-12-2021

Hi Srinivasa, As this is a 3rd party application I am not really sure about it. Glad that currently you have a property that help in achieving the goal.

@arunek95 Hi We tried the same steps which are in link but spnego keytab not generated after restarting cloudera manager . Please suggest some workaround for same.

arunek95 · ‎11-21-2021

We have to check from where the Ambari is triggering the command. If possible please share the relevant Ambari server error logs during the operation.
