Review Comment:
This test case is to refresh the configuration of two nodes in the cluster
that are in the decommissioning state. It is necessary to wait for the 'finish'
keyword of both nodes before the subsequent information verification becomes
meaningful.
> Use the dfsadmin -reconfig command to initiate reconfiguration on all
> decommissioning datanodes.
