I'm testing the CDH upgrade from v5.16.1 to v6.3.3. Cloudera manager server v6.3.3 upgrade was done successfully. But I have a trouble in Upgrading the Cloudera Manager Agents section. https://docs.cloudera.com/cdp-private-cloud/latest/upgrade-cdh/topics/ug_cm_upgrade_agent.html I can see The Upgrade Cloudera Manager Agent Packages page. But the Install agents fails due to Failed to copy installation files. I tried both repository location of Cloudera repository and custom repository but the both was failed.   I think inter hosts ssh communications are no problem because I tested ssh login b/w them and I confirmed the /tmp/scm_prepare_node.XXXXXXXX was made on target agent host. I suspects key handling is the cause but I'm not sure how to confirm it. Here's the cloudera-scm-server.log. (modified URL because it's raw username and password)   2020-10-06 14:54:10,500 INFO NodeConfiguratorThread-12-0:com.cloudera.server.cmf.node.NodeConfigurator: Executing mktemp -d /tmp/scm_prepare_node.XXXXXXXX on bsuhdpsv01 2020-10-06 14:54:10,528 INFO NodeConfiguratorThread-12-0:com.cloudera.server.cmf.node.NodeConfiguratorProgress: bsuhdpsv01: Transitioning from MAKE_TEMP_DIR (PT0.045S) to COPY_FILES 2020-10-06 14:54:10,736 INFO NodeConfiguratorThread-12-0:com.cloudera.server.cmf.node.NodeConfigurator: Using key bundle from URL: https://****usernameXXX:****password@archive.cloudera.com/p/cm6/6.3.3/allkeys.asc 2020-10-06 14:54:10,745 INFO NodeConfiguratorThread-12-0:com.cloudera.server.cmf.node.NodeConfiguratorProgress: bsuhdpsv01: Setting COPY_FILES as failed and done state 2020-10-06 14:54:10,745 INFO NodeConfiguratorThread-12-0:net.schmizz.sshj.transport.TransportImpl: Disconnected - BY_APPLICATION 2020-10-06 14:54:15,244 INFO scm-web-2446:com.cloudera.enterprise.JavaMelodyFacade: Entering HTTP Operation: Method:POST, Path:/add-hosts-wizard/installprogressdata.json 2020-10-06 14:54:15,246 INFO scm-web-2446:com.cloudera.enterprise.JavaMelodyFacade: Exiting HTTP Operation: Method:POST, Path:/add-hosts-wizard/installprogressdata.json, Status:200 2020-10-06 14:54:15,427 ERROR CommandPusher:com.cloudera.cmf.command.flow.WorkOutputs: CMD id: 1634 Failed to complete installation on host bsuhdpsv01. 2020-10-06 14:54:15,427 ERROR CommandPusher:com.cloudera.cmf.model.DbCommand: Command 1634(GlobalHostInstall) has completed. finalstate:FINISHED, success:false, msg:Failed to complete installation.   Best regards, Tak567 ...

Hi Community,   I'm looking for the training materials for CDH. I think there's no public materials about CDH. They seems to be for CDP, new products.(https://www.cloudera.com/about/training.html ) I also tried to check the partner portal but it's 404 link. https://www.cloudera.com/partner-portal/training.html   I have to upgrade CDH v5.16 to v6.3.3 and I'd like to learn the whole functions about CDH. (the ones written in Japanese are better if possible but I'm OK with them in English)   Best regards, Takuya Kohama ... View more
