Hello, If the Hue Kerberos Ticket Renewer does not start, check your KDC configuration and the ticket renewal property, maxrenewlife, for the hue/<hostname> and krbtgt principals to ensure they are renewable. If not, running the following commands on the KDC will enable renewable tickets for these principals: kadmin.local: modprinc -maxrenewlife 90day krbtgt/MY.REALM kadmin.local: modprinc -maxrenewlife 90day +allow_renewable hue/my-hostname@MY.REALM Thanks!

Question What are the minimum and maximum cluster sizes? Answer The minimum cluster size is 3 worker nodes, 1 Master node, and 1 Cloudera Manager node, for a total of five nodes. The maximum cluster size varies based on cluster type and public cloud. Further information about this could be found in this Cloudera Altus Documentation section NOTE: Each cluster spun up by Cloudera Altus requires 2 additional (master) nodes, one for CM and the other for Master services used for each cluster. These 2 nodes are a hard-requirement per cluster as they're required for a functional cluster and will need to be accounted for when calculating the public cloud instance limits.

Question Does Cloudera save AWS user credentials (AWS Access Key ID or AWS Access Key)? Answer No, Cloudera doesn't save AWS user credentials. If Cloudera Altus environment is set-up using the Cloudera Altus Quickstart, the user is prompted for these credentials, but they are never sent to Cloudera Altus. They are used by the web application residing within the user's brower that sends commands directly to AWS to create necessary resources using a CloudFormation script. In case of the Environment being created via Cloudera Altus Wizard, credentials will never need to appear inside the Cloudera Altus console. User needs to create necessary resources in AWS console and then grant access to them using AWS cross account access mechanism, which does not involve explicit key management.

Question Does Cloudera have access to the customer data in Cloudera Altus Clusters? Answer No. Cloudera Altus clusters are setup with the expectation that data will reside on the cloud provider's object storage (AWS S3, Azure ADLS). When data resides in this object storage (which exists inside a customer account within AWS or Azure), the Cloudera Altus service does not have access to this data.

Question What are the available cluster types in Data Engineering Cluster? Answer Currently, Cloudera provides clusters that can run the following Data Engineering job types: - Hive on MapReduce - Hive on Spark - Spark on YARN - MapReduce2 - PySpark Note: Job submission for a cluster is restricted to the type of job for that various cluster. For example, if you wanted to run just a MR2 job on a Spark-on-YARN cluster, you cannot submit this, even though Spark is configured to use YARN. You would need to standup a separate YARN cluster for it to accept a MR2/YARN job.

One more way to get low-level versions for everything: Hosts --> All Hosts --> Inspect All Hosts (button). This will return a report of CM and CDH packages.

Hello again, Vinay As it shown from the output of the executed commands, your system is not registered with RHN, so you won’t be able to download/update your system packages using the default repository. If you haven’t started your RHEL evaluation yet, then do it here https://access.redhat.com/products/red-hat-enterprise-linux/evaluation Also, make sure that your system has registered and subscribed, using these commands: # subscription-manager register # subscription-manager subscribe Then you can install your missing packages/dependencies. If the problem still exist, I would suggest to check your subscription issue with Red Hat. On the other hand, as a suggestion, you could try CentOS instead of RHEL, so you avoid the subscription issue, as CentOS is a free distribution of Linux. Let me know if you need any help! Thanks, Laith
