The cluster appeared to be up and running -- healthy. Attempts to create a table via the shell was hung in the CreateTableCommand, polling on the FATE operation. After a few minutes, it made no progress. > Inspecting the FATE transactions showed that there were (multiple) FATE ops running, but none where locked or locking any tables, nor making any progress. > This lead me to inspect the Master's log to figure out why it wasn't making any progress, and, to my joy, I found the following: > {noformat} > 2015-11-18 23:18:30,784 [fate.Fate] ERROR: Thread "Repo
