We have added a web server to Drill for showing query status information as well as setting configuration options like storage plugins. To view the storage plugin management interface you can go to localhost:8047 if you are running in local mode. If you are running from a cluster I believe you should be able to just substitute any of the IP addresses of the nodes, but I haven't been working with Drill in a clustered environment, so someone else might have to chime in with more info.
