Right, there's no data balancing right now unless you add more tablets/create new tables. If you can afford it, dump the table to Parquet, drop the table, create a new one (that will get the distribution you want), and finally reimport the data in the new table. Master has a new "relocate" tool that lets you move tablet, but it's kind of slow process: https://github.com/apache/kudu/commit/5b7626e3a8250d797f2fc2001c8ee7634a39d18b J-D On Wed, Aug 9, 2017 at 9:09 AM, Andrey Kuznetsov <[email protected]> wrote: > Hi folk, > > I have a problem with kudu: I need rebalance 8Tb of data due sizing > cluster with 3 new worker nodes, but it looks like it is not supported by > KUDU, is it? > > > > Best regards, > > *ANDREY KUZNETSOV* > > *Software Engineering Team Leader* > > > > *Office: *+7 482 263 00 70 *x* 42766 <+7%20482%20263%2000%2070;ext=42766> > *Cell: *+7 920 154 05 72 <+7%20920%20154%2005%2072> *Email: * > [email protected] > > *Tver,* *Russia * *epam.com <http://www.epam.com/>* > > > > CONFIDENTIALITY CAUTION AND DISCLAIMER > This message is intended only for the use of the individual(s) or > entity(ies) to which it is addressed and contains information that is > legally privileged and confidential.
