I am trying to lock down the security groups for an Accumulo/Hadoop/Zookeeper (AHZ) cluster in Cloudera Manager 5.16. The cluster should not be able to communicate outside of the VPC. I tried using a self-referencing security group that allows all traffic but that seems to have issues (ie: zookeepers arent peering, etc). Is there a way to configure security groups so that he AHZ cluster can not communicate with anything outside of the VPC? Due to environment restrictions, private subnets and NACLs are not an option.

Does tsquery have an in operator like SQL? I would like to make a dashboard query like "SELECT cpu_percent WHERE hostname IN (dev,test,prod)"

Thanks for the response. I have read over all of the provided links. Below are additional details: Configured external accounts using both Access Key Credentials and IAM role authentication. Neither works but I am not clear on what credentials need to be assigned to the IAM role or access key's account. Tried to setup a replication schedule for HDFS with each external account as the destination. Tried using "root" or root-like account on the underlying linux system(s) and "admin" from the cloudera gui. Tried both static and dynamic replication strategy No errors appear on the dialog and no errors appear in cloudera events or logs. Is there something else to check?

Hello, I am not having any luck setting HDFS replication with the S3 connector in CM 5.16. I have tried using both IAM Role-based Authentication and Access Key Credentials but neither seem to work. There are no error messages but nothing from HDFS is being replicated. Has anyone else had success with HDFS replication to S3?

Is there a cloudera feature to automatically send logs to cloudwatch/s3 or other external log collector. Using the CM API seems like a good good way to go but I can not find any documentation for sending log data collected from REST endpoints to cloudwatch. Is that a bad use case?

Can this be set in "Accumulo Service Advanced Configuration Snippet (Safety Valve) for accumulo-site.xml"
