Will Berkeley updated KUDU-2331:
    Code Review: http://gerrit.cloudera.org:8080/9510

Actually, the tool does use tablet id filters. The problem is that it insists 
all tservers be up to pass the pre-flight check. This is too restrictive.

> Use tablet_id filter for 'move_replica' while running ksck-based pre-flight 
> consistency check

> {\{kudu tablet change_config move_replica}} could use {{tablet_id}} filter to 
> perform pre-flight consistency check.  Right now, it always fails with 
> {{Network error: ksck pre-move health check failed: Not all Tablet Servers 
> are reachable}} error when whatever a tserver in the cluster is dead.  No 
> matter if the dead server is not involved in serving a replica of the tablet, 
> the command doesn't allow users to run it.
> The tool should allow moving a tablet replica when the destination server and 
> all tablet replicas are alive.
