Ivan Mitic commented on HDFS-4586:
----------------------------------
Seems to be a regression introduced with HADOOP-8973. TestDataDirs mocks based
on the previous implementation of DiskChecker#checkDir. This seems to be
breaking the layering of projects, and to prevent this from happening, I will
mock DiskChecker#checkDir instead. Will post a patch for this soon. Please
comment if you think differently.
