Service Monitor and Activity Monitor are the two heavy hitters. They both write to a TSDB on the local FS in a directory that you specify in the configs. I would split as I mentioned above: Host1: CM, DB, Amon, Rman Host2: Smon, Hmon, Event, Alert Service Monitor - resource usage dependent on the number of services being ran. It will grow as new nodes are added, as the new nodes will be running new services. Activity Monitor - Collection information on MR. Host monitor - Resource req. will depend on the number of hosts; will grow as new hosts are added. Reports Manager - Is all about the reports. This is usually light if only the pre-built reports are in place and generated. I have had to bump this up as the cluster usage and size grew. I haven't looked into it but it is likely because the reports run on a schedule even if they are not used. Event Server - Events can be generate out of any metrics or log entries. You can add more or more can be generated if they are triggered by changes to the system. Alert Publisher - Resource req. will depend on the number of alerts. This will grow with new hosts and services. More alerts can be added.

I have made it work finally, The issue is with PBI, After installing gateway it has it's own service account from which it connects to the driver which doesn't have access to so it's failing, I need to change the service account to windows service account with which I logged in service seetings in On premises Gateway (Power BI) and it worked Thanks a lot for your time Cheers

Ah, yes. I should have been clearer in my wording. I meant the VM itself. 🙂

The query executes with map reduce engine and I get the desired result. The error happens when I switch to spark engine.

CDH does not come with the Kafka parcel. You need to add that seperately. Check the list of available parcels. If it is not present add the remote repo for CDH Kafka and check for new parcels. If it is available, download, distribute, and activate. From CM Add a Service Wizard: "Apache Kafka is publish-subscribe messaging rethought as a distributed commit log. Before adding this service, ensure that either the Kafka parcel is activated or the Kafka package is installed."

Thanks for the answers. The described steps solve the DNS change for Manager indeed. For director, I will use a pre-baked Manager AMI as suggested.

Presumably, Kerberos is enabled or you wouldn't be getting this error at all. All users must have a valid ticket from a KDC. This typically means running kinit prior to running any commands or jobs. You can also get a ticket using a keytab file, which is just a store version of the users password. The ticket is store in the ticket cache on the system. By default it is /tmp/krb5cc_<userid>. The client will check here first for a ticket. I would venture that some other process is getting a ticket and storing it in the ticket cache and the other processes are able to use it. This is likely since you are using the 'hdfs' account that the HDFS processes are running under. I strongly encourage you to not operate in this fashion. Instead of using the 'hdfs' account update the Superuser Group setting in CM to include a group that you wish to have HDFS superuser access, which I assumed is why you are using 'hdfs' in the first place.
