Hi @Chetankumar , the mentioned configs are related to user group mapping in HDFS. May I know if yo have enabled these? Also do you want to change the bind user or only the searchbase?

Hi, You may want to change the new encryption type in your "krb5.conf" file also you can set the * Set "Active Directory Set Encryption Types " under > CM > Configuration * You may also want to include the new encryption type per the documentation ( CM > Configuration > "Kerberos Encryption Types" ) > https://docs.cloudera.com/cdp-private-cloud-base/7.1.6/security-kerberos-authentication/topics/cm-security-kerberos-authentication-regenerate-principals.html?#ariaid-title7 * Then you may want to Regenerate the credentials for all services to use the new encryption type ( stop all services is required to perform this )

I am using CDH 5.10

We have made changes to Static Service Pools in CM and now it failed to start the node manager. Could you please let me know how can we revert it back to original? This is cloudera express version. @Scharan

@Phantom No CDH4 is discontinued and not on internet as well. If you have old Internal Repository setup then you can try to install but from internet it's not possible. One way I can think of is try to manually place the parcels on the new node but again you might not have agent version so it will be a mess. If you are having a paid subscription then I would suggest you to upgrade to some supported version or AT LEAST publicly available version and then add node. Without Subscription New Node Addition is not possible.

HDFS data might not always be distributed uniformly across DataNodes. One common reason is addition of new DataNodes to an existing cluster. HDFS provides a balancer utility that analyzes block placement and balances data across the DataNodes. The balancer moves blocks until the cluster is deemed to be balanced, which means that the utilization of every DataNode (ratio of used space on the node to total capacity of the node) differs from the utilization of the cluster (ratio of used space on the cluster to total capacity of the cluster) by no more than a given threshold percentage. The balancer does not balance between individual volumes on a single DataNode. To free up the spaces in particular datanodes. You can use a block distribution application to pin its block replicas to particular datanodes so that the pinned replicas are not moved for cluster balancing. https://docs.cloudera.com/HDPDocuments/HDP2/HDP-2.6.0/bk_hdfs-administration/content/overview_hdfs_balancer.html

@Jaydeep_Ta The permissions are in place and owner is cloudera-scm user. It have 644 permission. I tried to install the same on 5.16 and it is working without any issues. Only 5.10 is having issue.

Hi @Chetankumar , I think we answered in this thread :- https://community.cloudera.com/t5/Support-Questions/How-to-move-block-from-one-mount-point-to-other-and-remove/td-p/314861 If that answers all your questions, feel free to mark the post "accepted solution" Regards,

Chetankumar · ‎04-20-2021

Hi @kingpin Thanks for your reply. Yes this solution worked and now we are able to remove the old disk and after rebalance new disks are in use. We will continue to remove the disk from each node after the rebalance complete after each attempt.
