      Description

      Started a cluster with 1 coordinator and 1 executor:

      bin/start-impala-cluster.py -c 1 --use_exclusive_coordinator -s 2
      

      Queries on Kudu tables still contained hosts=3, while all other table types had hosts=1.

      explain select * from functional_kudu.alltypestiny;
      Result:
      ...
      F00:PLAN FRAGMENT [RANDOM] hosts=3 instances=3
      ...
      

      The numbers in the plan are only estimates, the summary after the query contained 1 host.
