Andrew Wang commented on HDFS-4199:
-----------------------------------
Thanks for pulling me in Robert. I think you're right. Equality of the id's is
meaningless if they aren't valid. Right now we assume that users of
DFS#getFileBlockStorageLocations() know to check isValid() first, but better
would be to fix HdfsVolumeId to make all invalid ids equal, and not equal to
any valid ids.
