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,

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,

Hi @Bender , Thanks a lot for your answers. I will open a case in Cloudera Support for it. Kind regards, Daniel

Hi @Bender , I do have entries with INFO in the log file but I can't find any with nav_elements. I also have some errors and warnings: ERROR SparkPushExtractor [qtp1810923540-17908]: com.cloudera.nav.pushextractor.spark.SparkPushExtractor Error extracting Spark operation. java.lang.NullPointerException WARN ApiExceptionMapper [qtp1810923540-17908]: Unexpected exception. java.lang.NullPointerException ERROR SparkPushExtractor [qtp1810923540-17879]: com.cloudera.nav.pushextractor.spark.SparkPushExtractor Error extracting Spark operation. org.apache.solr.client.solrj.impl.HttpSolrServer$RemoteSolrException: Expected mime type application/octet-stream but got application/xml. <?xml version="1.0" encoding="UTF-8"?> <response> <lst name="error"><str name="msg">application/x-www-form-urlencoded content length (3820497 bytes) exceeds upload limit of 2048 KB</str><int name="code">400</int></lst> </response> I restarted Cloudera Management Server on July 29th.

HI @Bender Navigator Metadata Server Logging Threshold is set to INFO Thanks, Daniel

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,

Hi guys, thanks a lot for your answers. In the end, I restarted YARN and all its dependencies and after few minutes everything was ok . Thanks, D.

Hi guys, I'm getting this message: Concerning : YARN container usage metric aggregation failed because there is no active ResourceManager. Both YARN resource managers (Active and Standby) are up and running but YARN still shows me this error. Any idea why? Thanks, D.
