Hello @MikeZ ,   thank you for raising your question about Livy on CDH6. As you mentioned Livy is supported only in CDP [1] (Cloudera Data Platform 7), however it is not supported yet in CDH6. Usually a product is not supported until Cloudera finds it stable and production ready. Therefore we encourage you to evaluate CDP [2].   The "KerberosName$NoMatchingRule: No rules applied to mzeoli@COMPANY.PRI" exception usually occurs when the hadoop.security.auth_to_local rules does not provide a mapping to the local linux user (the user has to exist on the node that is extracted from the kerberos principal). Also make sure that the krb5.conf is readable by the user.   Please let us know if this information was helpful!   Kind regards: Ferenc   [1] https://docs.cloudera.com/runtime/7.1.0/running-spark-applications/topics/spark-submitting-applications-using-livy.html [2] https://docs.cloudera.com/cdpdc/7.0/installation/topics/cdpdc-trial-download-information.html ...

Hello @BSST ,   it is great to hear that you can add hosts on CDP now without issue and letting us know what did you do to overcome the problem. It will help other Community Members to follow your solution in a similar situation.   Regarding to the "Error 404 command has no file attached" message: - first of all, thank you for reporting it - can you please share the steps to reproduce this message, please?   Does it occur when you change the scope by any chance? Do you get the expected results apart from the error message displayed, please?   Kind regards: Ferenc ... View more

Hello @BSST ,   can you please check if you get an Error 113 ('No route to host') in /var/log/cloudera-scm-agent/cloudera-scm-agent.log and follow instructions under [1] to resolve the issue?   Furthermore please make sure you follow the Network and Security Requirements under [2]. I have checked internally and the section under "CDH and Cloudera Manager Networking and Security Requirements" applies to CDP, however please ignore the "Users and Groups" table, as these will be taken care of the automated installation. Just make sure the created users and groups are not modified/removed by anyone or any automation. The doc that will cover this section for CDP is on it's way for publication (thanks to your input on this missing piece!).   To answer your enquiry what does CM HA means: Cloudera Manager High Availability.   Thank you: Ferenc   [1] https://docs.cloudera.com/cdpdc/7.0/installation/topics/cdpdc-troubleshooting-installation.html [2] https://docs.cloudera.com/documentation/enterprise/6/release-notes/topics/rg_network_and_security_requirements.html ...

Hello @BSST ,   thank you for raising the question regarding the “Null value(s) passed to lookup by non-nullable natural-id” exception shown once the CM Agents reported being installed successfully.   There is a known issue reported for the trial version for CM HA mode that the agent is being reported as installed pre-maturely. This issue is not present in a non-HA environment. My understanding is that the agent would be installed after all.   Can you please confirm that you managed to install the agents successfully despite the odd message and if you are running in CM HA mode, please?   We recommend to use the trial version in a non-HA mode.   Thank you: Ferenc ...

Hello @BSST ,   thank you for updating us that cleaning the local client cache for the yum repositories did not resolve your issue connecting to Red Hat CDN.   Did you go through the "Known Issues" section in the Red Hat KB [1], please? Should the instructions in under "Known Issues" section did not help, please file a Support Ticket with Red Hat for further troubleshooting.   Please let us know once you overcome the 404 issue and you hit a problem again!   Best regards: Ferenc   [1] https://access.redhat.com/articles/1320623 ...

Hello @BSST ,   thank you for letting us know that the RedHat repo cannot be accessed.   Please follow [1] and if it does not help to resolve the repository issue, kindly reach out to RedHat Support for further troubleshooting.   Please let us know if you managed to overcome this obstacle.   Kind regards: Ferenc   [1] https://access.redhat.com/articles/1320623 ...

Hello @BSST ,   thank you for reaching out and raising this concern about missing link to Runtime and Cloudera Manager Networking and Security Requirements.   I have found the referenced link [2] for and earlier Cloudera Manager version (CM6.2) [1].   Let me action this internally and update this thread once we fixed the issue with the missing documentation for the CDP version.   Thank you again!   Kind regards: Ferenc   https://docs.cloudera.com/documentation/enterprise/6/6.2/topics/cm_ig_non_production.html https://docs.cloudera.com/documentation/enterprise/6/release-notes/topics/rg_network_and_security_requirements.html#cdh_cm_network_security     ...
