> 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.
