Patrick White commented on HDFS-8664:
-------------------------------------
Somethings messed up and I've lost the will to live for the day. After many
hundreds of runs without change, it eventually ran fine. So I'm mentally
marking this as a flaky test and I'll pick back up tomorrow.

> We have many disks per machine (12+) that don't always have the same
> numbering when they come back from provisioning, but they're always in the
> same tree following the same pattern.
> It would greatly reduce our config complexity to be able to specify a
> wildcard for all the data directories.
