Hello-

I'm trying to get Drill running on 6 of my (MapR / M3 / 3.1) nodes. 
Following the instructions 
(https://cwiki.apache.org/confluence/display/DRILL/Connecting+Apache+Drill+to+Data+Sources)

I get as far as attempting to configure dfs: and/or hdfs: from the 
Storage tab. When I select "Update" for dfs, it times out at the web 
browser with these errors in the log:

2014-06-17 09:31:21,756 [qtp204632028-62] INFO 
o.a.d.e.server.rest.StorageResources - Failure while trying to access 
storage config: dfs

setting up file system plugin.

~[na:1.7.0_51]

Similarly, when I attempt to create a new storage configuration "hdfs", 
it times out and the log reports this:

2014-06-17 09:37:06,562 [qtp204632028-72] INFO

service mapr-zookeeper qstatus shows that all 4 zookeeper nodes are running.

Any suggestions?

Thanks
