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 ...

Hi @Amn_468    In Kudu Table is divided into multiple tablets and those tables are distributed across the cluster. So the table data will be stored across multiple TS (kudu nodes)   You can get that info from Kudu master WebUI CM->Kudu ->Webui -> Tables ->select table    curl -i -k --negotiate -u : "http://Abcde-host:8051/tables"   Also, You can run ksck command to get that info :-  https://kudu.apache.org/docs/command_line_tools_reference.html#table-list   Does that answer your question, if yes please feel free to mark the post as solution accepted and give a thumbs up.   regards,   ...
