That's right, you'll need to look into how to setup AWS LB to have sticky sessions, which is not enabled by default. Also, please look into tuning the session timeout to a high value (long enough for Impala to finish the query and send the results back to Hue) Reference: https://docs.aws.amazon.com/elasticloadbalancing/latest/application/sticky-sessions.html Kind regards, Alex Akulov

Hi @yagoaparecidoti , If you have Impala daemons that are load-balanced (LB), then there is a configuration that needs to be applied on the LB, related to source IP persistance. There is a Knowledge Base article about this: https://community.cloudera.com/t5/Customer/Load-balancing-between-Hue-and-Impala/ta-p/73364 If there is no LB at play here, then has this issue been ongoing or just started to pop up recently? What changed on the cluster recently? Regards, Alex

Hi Andrea, There is not much different from how you would install R and SparkR on any other host. The steps to install would be the same. How that R runtime integrates with CDP DataHub would need to be configured after the installation. Instead of SparkR, I would actually recommend you use sparklyr, as it's more compatible with Spark. Regards, Alex

This likely needs attention from Cloudera support. Please open a case through your mycloudera portal. Regards, Alex

Hi @mmk , please provide what version of CDP you are using, on-prem or public cloud. Also see this documentation page for working with S3: https://docs.cloudera.com/cdp-private-cloud-base/7.1.7/cloud-data-access/topics/cr-cda-configuring-access-to-s3.html Kind regards, Alex

Ok, @aval, if you are after the CDP Base requirements that are needed to install CDP Data Services (formerly experiences), then check the list at the bottom of this page: https://docs.cloudera.com/cdp-private-cloud-data-services/1.3.4/installation-ecs/topics/cdppvc-installation-base-software-requirements.html For all dependencies between various services, you can consult this table: https://docs.cloudera.com/cdp-private-cloud-base/7.1.7/installation/topics/cdpdc-service-dependencies.html Hope this helps, Alex

CDP 7.x uses parcels through Cloudera Manager. RPMs are no longer provided. Regards, Alex

Hi @aval , These are all great questions. You mentioned that these are licensed installations, so you may want to work with the account team from Cloudera to answer these questions. There is a lot of detail that would not be tractable to cover in a forum post. If you are not sure who to talk to, open a support case with Cloudera and ask to be connected with the account team for your enterprise. Best wishes, Alex

Happy to hear, @Data1701 . Accept reply as Solution if the answer helped.

Hi @Jaguare , What you likely want to use is not sqoop, but hdfs' native distcp command. There are guides on the internet on how to do this. A quick google found this: https://docs.microsoft.com/en-us/azure/hdinsight/hadoop/apache-hadoop-on-premises-migration-best-practices-data-migration Hope this helps. Regards, Alex
