Hi all, my team are currently testing on HDFS rebalancing in a HDFS cluster with two DataNode. I have read the documentation https://docs.cloudera.com/cdp-private-cloud-base/7.1.6/scaling-namespaces/topics/hdfs-step-1-storage-group-classification.html We have a few question about how the file moving size is calculated. 1. How is cluster average utilization calculated. Do the calculation use Configured capacity or Present capacity? 2. How is individual utilization calculated. Do the calculation use configured capacity or the sum of DFS used and remaining? 3. When looking at the balancer log, it said need to move 4.98GB to make the cluster balanced. However, afterwards, the log show that the balancer decided to move 18.98GB from one host to another host. Why there is difference? Balancer log 4. We have set the DataNode balancing bandwidth to 200MiB, but as per observation, the bandwidth consumption can exceed 200MiB. Why did it happen? Please help me with my questions. Thank you in advance.

Do you confirm that you can do login from one node to another node using ssh?

Hi all, Recently I am practicing Apache Atlas and my cluster enabled Kerberos. After I created a Hive table using hive service principle, I use an AD account to access Atlas console. However, when I search for hive process, no record appears. I have checked the integration between Hive and Atlas in Hive configuration. Do I need to create a ranger policy and grant read permission to the AD user? If yes, please kindly suggest how to set the ranger policy. Thank you in advance. Looking forward to hearing from all of you.

I finally managed to solve the problem by switching the OpenJDK version from 8u362 to 8u232. However, is OpenJDK 8u232 the only version that support when working on CDP 7.1.8 with Kerberos enabled? Could someone clarify it for me please? Thank you.

Thank you for your help @kolli_sandeep . Finally I made an API call to interrupt the Parcels activation, then remove the corresponding Parcels file and the ./flood folder in /opt/cloudera/parcels. The parcels can successfully redistribute and activate after that.

Hi all, I have a CDP 7.1.8 cluster running in my environment. Recently, I would like to try enabling CM server High Availability. I studied the instruction in this link https://docs.cloudera.com/cdp-private-cloud-base/7.1.8/managing-clusters/topics/cm-ha-configure-steps.html. My question is, currently I have tried migrating the CM server to another host and I cannot see my cluster on the new CM server console until I manually restore the cluster. I really doubt that after I enabled CM server HA, when the system failover to the passive CM server, I will not see my cluster as well. Could someone clarify for me please? Thank you very much.

Hi all, I have a CDP 7.1.8 cluster running in my environment. Recently I would like to migrate the existing CM server to another host. I followed the instruction in the link https://docs.cloudera.com/cdp-private-cloud-base/7.1.8/managing-clusters/topics/cm-moving-the-cm-server-new-host2.html. After that, the CM server is successfully migrated to the target host and I can see the cluster node recognized by the new CM server. However, I cannot see the cluster appear on the new CM server console. Finally, I have to manually restore the cluster using the link https://docs.cloudera.com/cdp-private-cloud-base/7.1.8/configuring-clusters/topics/cm-api-import-configuration.html. My question is, am I suppose to restore the cluster manually? What I expected is I can see the cluster immediately without extra work done after switching CM server. Could someone clarify for me please? Thank you.

From the system log, I found error saying unsupported Keytype. I am using OpenJDK 8u332. Do anyone know how to solve this? Thank you.

Hi all, I have a cluster in CDP version 7.1.8 private cloud base. The Cloudera Management service show bad health and indicate that the connection to KDC server is not available. I can regenerate missing credentials under Administration > Security > Kerberos Credentials Moreover, I can do kinit in the CM server host. Therefore I have no idea why the connection shows failure. Please let me know if I should provide further information. Thank you.
