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 @Plascio , It should be possible by using the CDP trial versions. Please go through this document and you can try the setup after verifying the requirements for OS and network. https://docs.cloudera.com/cdp-private-cloud-base/7.1.6/installation/topics/cdpdc-trial-installation.html

Hi @maali_87 , We can gather the clear text password from the Cloudera server DB. Please try this command after logging to CM DB - select * from CONFIGS where ATTR='auto_tls_truststore_password';

Hi @luobo2019 , Are you still facing the same issue after following the step 1 ? Can you please share the Ambari server logs when you see the message in the UI. Also please try to check the inspect element of the browser while replicating the issue.

HI @drewski7 , Can you please help us with the API you have used and the failure logs as well to check.

Hi @luobo2019 , Can you please try the below 2 things and let me know how it goes - Resolution 1 - Step 1: cat /etc/ambari-server/conf/ambari.properties | grep ambari-server.user. Know the user from above command. Step 2: change user /var/run/ambari-server chown -R <output of above command> /var/run/ambari-server Resolution 2 - Take Ambari DB backup 1. Query the ambari.alert_current and ambari.alert_history tables, look at the 'definition_id' and 'alert_definition' columns in these tables. 2. Look at the alert_definitions table select definition_id from ambari.alert_definition; and check the definition IDs. 3. Look for any definition IDs referenced in the alert_current and alert_history tables that are not present in alert_definition. 4. In ambari.alert_current, remove any row that references a definition ID that is not present in alert_definition 5. In ambari.alert_history, remove any row that references a definition ID that is not present in alert_definition

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.

arunek95 · ‎12-22-2022

Hi @bananaman , Can you please refer the below docs and enable the user search first and see if it helps. https://docs.cloudera.com/cdp-private-cloud-base/7.1.3/security-ranger-authentication-unix-ldap-ad/topics/security-ranger-authentication-ad-integration-usersync.html Also please try to run ldapsearch to see if it is able to list all the users.

Hello @Ujwal , Were you able to make any progress with the usecase you are trying ? Please help us with updates on this thread.

arunek95 · ‎09-08-2022

Hi @Ujwal , Does this happens when you directly hit the Atlas URL instead of Knox ? Can you check the Atlas application.log file to see any error or warn when you trigger the curl command. Also check the knox logs for any error. Thanks.

arunek95 · ‎09-08-2022

Hi @Kamal_Securonix , Can you please help us with the screenshot of the error and do you see anything in the CM server logs during the issue time ?

arunek95 · ‎08-26-2022

Hi @Ivoz , Thanks for reaching out. Usually during the migration of Atlas data you need to take backup of both the Hbase tables and Solr collections. Only migrating the Hbase tables won’t help here. Also at present Cloudera do not support the migration of Atlas from Open source to CDP. I am sharing a KB that have full insight of HDP to CDP Atlas migration steps (Specially check the steps of taking backup of Hbase and solr) , you can refer that and try to give a shot to see if it works. - https://community.cloudera.com/t5/Community-Articles/HDP-to-CDP-Atlas-backup-and-restore/ta-p/347457 Thanks

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 , @YHYH , It looks like to enable httpfs in HDP we have a different set of steps. Please refer this article and let me know if it is helpful - https://community.cloudera.com/t5/Community-Articles/HTTPFS-Configure-and-Run-with-HDP/ta-p/244340

arunek95 · ‎06-02-2022

Hi @gianluca , While editing the entity can you please try to do a tail -f on the atlas application.log and see if it is throwing any error and share with us also.

arunek95 · ‎05-18-2022

Hi @Christ , Apologies we were not able to get a solution for this issue. We request you to please create a Cloudera case in our portal to take it forward. Thanks

arunek95 · ‎05-05-2022

Hi @Christ , What I understood is you are importing a business metadata in Atlas UI and not seeing some attributes in the UI. Was the upload successful ? Have you noticed any error in the Atlas application logs ? Is it possible for you to share the .csv file to test it on our lab ?

arunek95 · ‎03-14-2022

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.

arunek95 · ‎03-14-2022

Hi @HDP_Suja , From the error " Execution of '['/usr/bin/yum', '-d', '0', '-e', '0', 'check', 'dependencies']' returned 1. hadoop_3_1_5_0_152-yarn-3.1.1.3.1.5.0-152.x86_64 has missing requires of hbase_3_1_5_0_152 phoenix_3_1_5_0_152-5.0.0.3.1.5.0-152.noarch has missing requires of hbase_3_1_5_0_152" It looks like it is still pointing to the old repo. Please check for any old repo under /etc/yum.repos.d and move it to another folder and restart agent to see if it works. Thanks

arunek95 · ‎01-24-2022

Hi @Koffi , May I know what Ambari version you are using ? And what was the change performed on those Hbase hosts ? Also can you check the Ambari server and agent logs on both the Hbase master nodes and check specifically for any JMX or ssl related error.

arunek95 · ‎01-24-2022

Hi , What I understood is you want to move the NameNode role to another host in the cluster. If my understanding is correct , then please follow the below document which shares insight on the same. https://docs.cloudera.com/documentation/enterprise/6/6.3/topics/admin_nn_migrate_roles.html#cmug_topic_5_17 The process should be same across CDP and CDH as we are using CM to migrate the roles.

arunek95 · ‎12-15-2021

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.

arunek95 · ‎12-14-2021

Hi @MahmoudSabri , Please use the snapshot policy provided by CM to create snapshot for HDFS or Hbase. Refer the doc - https://docs.cloudera.com/runtime/7.2.10/data-protection/topics/hdfs-create-snapshot-policy.html Hope this will help.

arunek95 · ‎12-13-2021

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 Mahmoud, I see you want to backup/restore the master nodes of the CDP cluster. May I know if you are planning to backup the HDFS data or the host data ? If it is the HDFS data then you can refer this doc - https://docs.cloudera.com/cdp-private-cloud-base/7.1.6/data-protection/topics/hdfs-perform-a-backup-of-the-hdfs-metadata.html And if you are planning to backup the host data then snapshot can be a good approach.
