Hello, I would like to know if it's possible to revert or reinstall an older version of Cloudera Manager. I have the following case: the current CDH and Cloudera Manager are both running on version 5.16.2. I have a request to upgrade only Cloudera Manager to 6.3.3. Now, I would like to know if it's possible to revert/reinstall to CM 5.16.2 in case the CM 6.3.3 version will not work as expected on CDH 5.16.2. Thank you,

Hello, I have a cluster that currently runs with CDH and Cloudera Manager version 5.15.2 for both and I would like to upgrade only Cloudera Manager to 6.3.3. Is there any issue running the cluster with these different versions of CDH and CM? Thank you,

Hello @Bender , Thanks a lot for your fast answer. The CDH version I am using is 5.15.2. I checked the Development cluster and there I can find the number of elements in the log file but in the Production cluster, it's not possible. Thank you, Daniel

Hello, I have a Production cluster and I get out of memory errors for Navigator Metadata Server. This is generating large dump files (33GB last time) in /tmp. Since /tmp has only 50GB it get's full quite fast. Errors: The health test result for NAVIGATORMETASERVER_UNEXPECTED_EXITS has become bad: This role encountered 1 unexpected exit(s) in the previous 5 minute(s).This included 1 exit(s) due to OutOfMemory errors. Critical threshold: any.
The health test result for NAVIGATORMETASERVER_DATA_DIRECTORY_FREE_SPACE has become unknown: Not enough data to test: Test of whether the Navigator Metadata Server Storage Dir has enough free space. There is a formula to estimate the optimal Java Heap Size for Navigator Metadata Server but the problem in my case is that in the cloudera-scm-navigator log file there is no nav_elements nor nav_relations. Is there any way to estimate the optimal java heap size? Current value is set to 24GB. Formula: ((num_nav_elements + num_nav_relations) * 200 bytes) + 2 GB Link from Cloudera Docs Thank you,
