Compacting Operation Stuck and Unable to Cancel (2.0-Beta)

This applies to the 2.0-Beta version just released. Created a cluster of 3 nodes with 3 buckets. As I began inserting data across the 3 buckets, the admin console alerted that the buckets were compacting. After a while, I'm left with a single message of "Compacting bucket parameters" that will not go away. If I look at the 'Data Buckets' tab and expand my 'parameters' bucket, I see "Compaction: 84% complete" with no progress happening. Attempting to click the Cancel button throws an error:

"An error was encountered when requesting data from the server. The console has been reloaded to attempt to recover. There may be additional information about the error in the log."

From the log:
