> If DN is deleted the hostname is removed from exclude file and refreshnodes command is
called. If those actions are not followed by NN restart, the deleted DN will be shown as DEAD
on NN UI.
> The slave should be removed by NN from the UI, but Ambari should not call refreshnodes
command on deletion to ensure slave is in "decommissioned and dead" state, not "dead"
