             Summary: Rebalance fails when trying to decommission tserver on a rack-aware cluster
                 Key: KUDU-3346
                 URL: https://issues.apache.org/jira/browse/KUDU-3346
             Project: Kudu
          Issue Type: Bug
    Affects Versions: 1.15.0
            Reporter: Georgiana Ogrean
         Attachments: rebalance_v1.log.Z

When following the steps [in the docs|https://docs.cloudera.com/runtime/7.2.0/administering-kudu/topics/kudu-decommissioning-or-permanently-removing-tablet-server-from-cluster.html] for decommissioning a tserver, the rebalance job fails with:
{code:java}
Invalid argument: ignored tserver <tserver_uuid> is not reported among know tservers 
{code}

Steps followed:
1. Checked that ksck passes.
2. Put the tserver to be decommissioned in maintenance mode.
{code:java}
sudo -u kudu kudu tserver state enter_maintenance $MASTER_ADDRESSES 5ae499b1b870419daabb0e8da90ef233 {code}
3. Ran rebalance with {{-ignored_tservers}} and {{-move_replicas_from_ignored_tservers}} flags.
{code:java}
sudo -u kudu kudu cluster rebalance $MASTER_ADDRESSES -move_replicas_from_ignored_tservers -ignored_tservers=5ae499b1b870419daabb0e8da90ef233 -v=1{code}

The logs for the rebalace command are attached.
