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 ... View more

Re: CDP Public - install R and SparkR

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  ... View more

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 ... View more

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 ...

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 ... View more

Hello @Data1701 ,   The metrics you are looking for would be under the Hosts view in Cloudera Manager. On the left-hand panel in Cloudera Manager click on Hosts > All Hosts. This will list all of the hosts in the cluster, along with their physical memory and cores for each. Note that, by default, not all of the necessary columns may be visible in the table. To add columns of interest (e.g. cores), in the top right corner next to "Columns:" click Selected dropdown menu and choose the columns you need to see.   Hope this helps.     Regards, Alex ...

Re: Grafana for visualization of CDP data

@THR-Mario , if you want to use Grafana as a general-purpose data visualization tool, then unfortunately that's not its purpose. Grafana is meant for time-series visualization, and in the context of CDP is used for metrics monitoring. In this task Grafana is great!    If you want to use Grafana to query Hive, Impala, or other large datasets, you will have a bad time. Sorry, that's not what you want to hear, but that's the reality.    Regards, Alex ... View more
