Adar Dembo commented on KUDU-1534:
----------------------------------

bq. Did you also mean kudu-client when you said 'master/client combination' 
above ?

Yes and no. I didn't see a simple way to bang on the ListTabletServers RPC with 
the C++ or Java clients, so that's why I suggested running kudu-ksck in step 4. 
It doesn't use the C++ client directly, but it will issue that RPC and process 
the response.

Alternatively, you can write a small C++ program that invokes 
KuduClient::ListTabletServers(), or a Java program that invokes 
KuduClient.listTabletServers(), build it against the appropriate 0.10.0 client 
library, and run that. But I was trying to save you from having to write new 
code.

> KUDU-1490 exposed the software version of tablet servers in the 
> GetTabletServers RPC response, but an equivalent doesn't exist for 
> ListMasters response.  This will become more important as multi-master setups 
> get more common.
