@snm1523 Hello, Thank you for bringing this to our community. I am pleased to share the benefits of considering our CDP Private Cloud. https://docs.cloudera.com/cdp-private-cloud/latest/benefits.html It is unfortunate that I cannot share insights about HPE Ezmeral or make a comparison. However, I am very confident that our Presales-Engineers would love to discuss with you on how you can benefit by using CDP-PvC: https://www.cloudera.com/contact-sales.html Let me know your thoughts on this. Cheers V

@Alfa6 Excuse me for the delayed update. I am catching up to speed here: In the meantime we would like to be sure that we will have not any regression about our software developed on CDP 7.1.1.

If not already, Please do: CDP 7.1.1 Components Version: https://docs.cloudera.com/runtime/7.1.1/release-notes/topics/rt-runtime-component-versions.html CDP 7.1.9 Components Version: https://docs.cloudera.com/cdp-private-cloud-base/7.1.9/runtime-release-notes/topics/rt-pvc-runtime-component-versions.html Additionally, Since you are concerned about the Backward compatibility, You may want to read the deprecation notices for 7.1.9 too: https://docs.cloudera.com/cdp-private-cloud-base/7.1.9/runtime-release-notes/topics/rt-pvc-deprecated.html Let us know how you plan your CDP upgrade.

Hey @hadoopranger Upon further research, I see the reqs for IBM-Cloudera Impala JDBC Driver here[0a] Lets make sure this is followed. [0a] https://www.ibm.com/docs/en/cognos-analytics/11.1.0?topic=troubleshooting-cloudera-impala-jdbc-drivers Since this is intermittent, see if there are any timeouts/retries presents on the BI Application layer or LB layer. We still want to know how the BI tool is connecting to Impala. Is it via LB or Impala daemons directly? If the Impala CLI is working as expected, You can try the following: 1. Timeout/Retries logic on the LB for client connections. 2. Try recreating your JDBC connections and implement retry logic within your app and restart the client app. 3. Also, Attaching the IBM Cognos User Guide for your reference: https://www.ibm.com/docs/en/SSEP7J_11.1.0/com.ibm.swg.ba.cognos.ag_manage.doc/ca_manage.pdf If you still need further help, I encourage you contacting contacting IBM Community for specific configs on the Data Sources. Let us know how it goes. Cheers V

Hello @hadoopranger Thank you for bringing this to our community. As you highlight, this looks to be intermittent connectivity issue with the Impala and the Client(BI Tool). Q. May we know what is the name and version of BI tool you are using? Also, You may want to review some of the related parameters/configuration from the tool. Max Wait Time Max Connection Lifetime Let us know how it goes. Cheers V
