Hello, I have noticed in one of the charts (HDFS IO) available in CM dashboard for HDFS that runs below query have got values pulled from 2 separate entities for the same metric. Attached are the 3 screenshots for reference. 2 graphs showing values from individual entities and 1 the combined graph available in CM that triggers below query. select total_bytes_read_rate_across_datanodes, total_bytes_written_rate_across_datanodes where category = SERVICE and serviceType = HDFS and clusterId = "1" Two different entities are hdfs and hdfs:<cluster_name> I have also verified the response from below API call, and it does returns both entities and both have latest data. http://<cm-host>:7180/api/v19/timeseries?query=SELECT%20total_bytes_written_rate_across_datanodes%20WHERE%20category=SERVICE What do they mean? Where are they coming from? How to get it fixed so a single value is returned for the metric? Kindly advise. Thanks Snm1523

Hello @snm1523 Add Connection: close header to your curl requests to ensure the connection is closed after each request. Alternatively, use --no-keepalive in the curl command to prevent persistent connections. If necessary, adjust server settings to force connections to close after each request.

Thank you @upadhyayk04. This helped.

For the benefit of anyone if looking for a solution to this. We need to add the -javaagent parameter in "Additional Broker Java Options" configuration property instead of what mentioned in in the post.

Error Code: ATLAS-404-00-007 Invalid instance creation/updation parameters passed: type_name.entity_name: mandatory attribute value missing in type type_name." This error indicates that when creating or updating an entity (likely in Apache Atlas or a similar system), a required attribute value for that entity is missing or not provided. Specifically, the entity's type (indicated as type_name.entity_name) is missing a mandatory attribute value defined for that type. Error Code: ATLAS-400-00-08A This error typically occurs when you're trying to upload or import a ZIP file that is either empty or does not contain any valid data. Verify that the ZIP file you're attempting to upload actually contains data. Check the contents of the file and ensure that it's not empty. If it should contain data, try recreating the ZIP file or ensure it's properly packaged before importing.

So do you mean that there is no need of migration, just bring up the new server, assign required roles and then decomm the old one?

@snm1523 Hello, Thank you for bringing this to our community. I am pleased to share the benefits of considering our CDP Private Cloud. https://docs.cloudera.com/cdp-private-cloud/latest/benefits.html It is unfortunate that I cannot share insights about HPE Ezmeral or make a comparison. However, I am very confident that our Presales-Engineers would love to discuss with you on how you can benefit by using CDP-PvC: https://www.cloudera.com/contact-sales.html Let me know your thoughts on this. Cheers V
