Based on this thread, it seems like the following command may be an option.  I will wait for further guidance, though.

 

./hdfs haadmin -transitionToActive <nodename>

I continued the resolution of this issue in another thread specific to the error: 

 

ls: Operation category READ is not supported in state standby

 

The solution is marked on that thread, however, a quick summary was that I needed to add the Failover Controller role to a node in my cluster, enable Automatic Failover, and then restart the cluster for it all to kick in.
