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. ... View more

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. ...
