Description

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.
