It is possible to use the kudu cluster rebalance tool to establish the placement policy on a cluster. You can run the manual rebalancer in report-only mode ('kudu cluster rebalance --report_only') and see what it says. So, I think it will be good to rebalance the new added range partitions. duplicates. sudo -u kudu kudu cluster rebalance In the first phase, the location-aware rebalancing process tries to reestablish the placement policy. This includes the ability to create, drop, and alter tables as well as read, insert, update, and delete data. Issue Links. The rebalancer can be run via kudu cluster rebalance sub-command. It seems that not only the new added tablets of this table but also the historical tablets will be rebalanced. User - principals authorized as a user are able to access and modify all data in the Kudu cluster. The Kudu 1.13 Java client library is API- and ABI-compatible with Kudu 1.12. I found it may be the problem in RebalancerTool::AlgoBasedRunner::GetNextMovesImpl when building extra_info_by_tablet_id, it check that the table id in tablet must occur in table info.But when we build ClusterRawInfo in RebalancerTool::KsckResultsToClusterRawInfo we only collect the table occurs in location but all tablets in cluster. ; Run the kudu cluster rebalance tool, supplying the --ignored_tservers argument with the UUIDs of the tablet servers to be decommissioned, and the --move_replicas_from_ignored_tservers flag. Using the new tool, it’s possible to rebalance Kudu clusters of version 1.4.0 and newer. It would be useful to be able to rebalance a list of tablets across a set of tablet servers in the case that the distribution of tablets became very imbalanced or a new tablet server was added to the cluster. ; Put the tablet server into a maintenance mode by using the kudu tserver state enter_maintenance tool. Attachments. The kudu cluster rebalance tool can reestablish the placement policy if it is possible to do so. The kudu cluster rebalance tool can also be used to establish the placement policy on a cluster if the cluster has just been configured to use the rack awareness feature and existing replicas need to be moved to comply with the placement policy. Internally, Kudu has a third access level for the daemons themselves. If a Kudu 1.13 cluster is configured with authentication and encryption set to "optional" or "disabled", older clients will still be able to connect. Use the --disable_policy_fixer flag to skip this phase and continue to the cross-location rebalancing phase. Ensure the cluster is in good health using ksck. Incompatible Changes in Kudu 1.13.0 Client Library Compatibility. Resolved; Activity. KUDU-886 Cluster load balancing. But the historical tablets already have data, so they are heavy to move and it will increase the disk and network suddenly. (note: CDH 5.16.1 doesn't include everything new from Kudu 1.8.0, only a few things like the rebalancer, but CDH 5.15.1 includes everything from Kudu 1.7.0 and earlier) This might be necessary when the rack awareness feature is first configured or when re-replication violated the placement policy. When we need to remove some tservers from a kudu cluster (maybe just for saving resources or replacing these servers with new servers), it's better to move all replicas on these tservers to other tservers in a cluster in advance, instead of waiting for all replicas kicked out and evicting new replicas.
