move_replica isn't available in CDH 5.12 / Kudu 1.4. It's first available in CDH 5.13 / Kudu 1.5. There's a few solutions:
1. Running move_replica against a 5.12 cluster using a 5.13 or later kudu tool should work. 2. You can move replicas manually using add_replica to add the new replica, waiting for the new replica to tablet copy and bootstrap, then removing the unwanted replica with remove_replica. The easiest way to do this is to monitor the status of the tablet with ksck while you're moving replicas (it's essentially what the move tool does internally). 3. Upgrade to 5.13 or later. -Will On Tue, Jan 2, 2018 at 4:59 AM, Beata Jursza <beata.jur...@onmarc.nl> wrote: > Hi, > > > > > > I need to migrate kudu tablets from one tablet server to another. > > I have run `kudu remote_replica list’ to determinate which tablets I want > to move, after that I have tried to use kudu tablet change_config > move_replica tool for migration however I got below message: > > Invalid argument: unknown command 'move_replica' > Usage: > /opt/cloudera/parcels/KUDU-1.4.0-1.cdh5.12.1.p0.10/bin/../lib/kudu/bin/kudu > tablet change_config <command> [<args>] > > <command> can be one of the following: > add_replica Add a new replica to a tablet's Raft configuration > change_replica_type Change the type of an existing replica in a tablet's > Raft configuration > remove_replica Remove an existing replica from a tablet's Raft > configuration > > Do you have any ideas how can I migrate kudu tablets? > > Thank you in advance > > > > Met vriendelijke groet, > > Best regards, > > > > *Beata Jursza* > > > > [image: cid:image001.png@01D2973B.4357FC30] > > E: *beata.jur...@onmarc.nl <beata.jur...@onmarc.nl>* > > T: +31 (0)30 636 3900 <+31%2030%20636%203900> > > M: +31 (0)6 83673664 <+31%206%2083673664> > > >
