Kudu Tablet Server Data Directories rebalancing

Hi,

 

We have 4 kudu tablet server data directories as 4 mounted separated disks on server.

We want to add new disk to the server and mount it as 5 kudu tablet server data directory. Is there a way to rebalance kudu data beetween all 5 disks?

 

Thank you in advance

 

Kind regards,

 

Master

I had a issue with even removing the data directory, but newer Kudu versions support this. As far as I know rebalance is only supported when you add a new Tablet server - there is no such thing like intra node rebalance in Kudu (such HDFS has)

Tomas is correct; the latest version of Kudu can support adding / removing directories, but cannot rebalance the data usage across Kudu data directories. FYI, I filed a tracking JIRA for this feature request at https://issues.apache.org/jira/browse/KUDU-2577
