@supahcraig,   I am glad you were able to resolve the problem. Usually if the upgrade stalls during distribution you can view details about which hosts have successfully downloaded the parcel via the the parcels page.  Clicking the progress bar will open a page that shows the progress for each host. Once you find a host or hosts that have errors or are not completing, you can mouse over or click on the bar to view more details including the hostname.   Once you have the hostname, you can ssh to that host and review the agent log there (/var/log/cloudera-scm-agent/cloudera-scm-agent.log)   The agent actually downloads the parcel file so you can see information about any problems in the agent log.   Here is a page that shows more about the parcels: https://www.cloudera.com/documentation/enterprise/5-9-x/topics/cm_ig_parcels.html     Cheers! ...
