Íñigo Goiri commented on HDFS-13336:
------------------------------------
Should we push this change into the MiniDFSCluster itslef and make the path for
it to be randomized always?
[~chris.douglas], this is the root cause for most of the failed unit tests in
Windows.
MiniDFSClusters left behind and not properly cleaned; in Windows the file
descriptor are also locking so no new tests can run.
We should improve the resilience of the tests to cleanup properly but this
could be a fix for now.
