@CaptainJa The version of Tomcat used in CDH 5.16.2 should not have any vulnerabilities. Could you share the CVE that is reported CDH is vulnerable to? Per the notice [1] independent upgrade of Tomcat is not supported and we are moving towards newer versions in CDH6 => Cloudera Enterprise 6 has replaced Tomcat 6 with Jetty 9 and is not susceptible to Tomcat security issues.

Hi @srik123 Apache Druid is not part of the CDH distribution and is not supported by Cloudera on the CDH platform. You can see the underlying Apache projects that are included and supported by Cloudera (in CDH) here: https://docs.cloudera.com/documentation/enterprise/6/release-notes/topics/rg_cdh_63_packaging.html#cdh_630_packaging In a similar way to the answer that was given to one of your other questions here you can install and configure third-party components on top of CDH - but they won't be supported by Cloudera. Here is an example of someone who has done this previously with CDH and Apache Druid: https://github.com/knoguchi/cm-druid Regards, Steve

Hi @satyap The Cloudera Distribution of Hadoop (CDH) can be deployed across data centers. Please take a look at this section of the Cloudera Bare Metal Reference Architecture: Appendix A: Spanning Multiple Data Centers Please pay close attention to the networking section. I generally do not recommend this topology because of the latency challenges that are introduced going across data centers. Regards, Steve

Hi @ahmedalsaidi Apache Nifi does not have a generic CDC processor as such. One way you can achieve a CDC like approach is to use the QueryDatabaseTable processor. Please take a look at this article on how to use the QueryDatabaseTable processor to do an incremental fetch of new rows in the source database: https://community.cloudera.com/t5/Community-Articles/Incremental-Fetch-in-NiFi-with-QueryDatabaseTable/ta-p/247073 Alternatively, you use can use a vendor that specializes in CDC. Please accept this answer as a solution if it helps you. Steve

Hi @mranjank In your setup, your 4 data nodes are your worker nodes. HDFS i.e. where the data are stored is on the data nodes and because of data locality, this is where your 'compute' or 'worker' nodes run too. If you log into Cloudera Manager and click 'Hosts' at the top and then 'Roles' on the dropdown you will see what services are running on what nodes. I hope that helps. Steve

Hi @piosobc , The CDH pricing is under the 'Enterprise Data Hub' column on this page: https://www.cloudera.com/products/pricing.html So yes, it's the same as CDP. But as @cjervis mentioned in an earlier post it is best to discuss this with someone in our sales organization via Contact Us page on Cloudera.com. I think Cloudera Express will work > 100 nodes for CDH / CM 6.0 as this limit was introduced at 6.1. However, I don't recommend this as an approach as you would surely benefit from the enterprise-class features for more than 100 nodes. Also, as I mentioned in my earlier post, Cloudera is moving away from shipping Cloudera Express editions. Your best option is to consider a support version of CDH / CDP. Regards, Steve

Hello, You can follow the steps outlined here. This is for CDH 6.3: https://docs.cloudera.com/documentation/enterprise/6/6.3/topics/cm_mc_adding_hosts.html#cmug_topic_7_5_1__title_215 Regards, Steve

Hello, Unfortunately, there is no way to independently upgrade Cloudera Hue within the VM. You would need to upgrade all of CDH 5.13 to the version that you require e.g. CDH 6.3. As far as I am aware there are no plans to provide new releases of the QuickStarts based on later versions of CDH. That said it is quite straightforward to install a trial proof-of-concept CDH cluster (for example you could do this on a single node using cloud-based infrastructure): https://docs.cloudera.com/documentation/enterprise/latest/topics/cm_ig_non_production.html#install_embedded_db Regards, Steve

Hi, No, CDH and the components under CDF are licensed separately. In your case, where you want to use Apache Nifi you would license Cloudera Flow Management which includes Apache Nifi and Nifi Registry. Regards, Steve
