HDFS-7917 below, DataNodeTestUtils.injectDataDirFailure() won't work for Windows as rename will fail due to open handles on data node dir. This ticket is opened to skip these tests for Windows.
Unfortunately, I just remembered that the rename isn't going to work on Windows. It typically doesn't allow you to rename a directory where there are open file handles anywhere in the sub-tree.

By doing that, we'd be changing the meaning of the test from covering an online failure to covering a failure at DataNode startup, so I don't think we can make that change.
Below are the two test cases that need to be fixed:
