Suresh Srinivas commented on HDFS-4752:
---------------------------------------

Chris, I agree with your analys about disable the test on Windows, instead of adding complexity
of config hooks. +1 for the patch.

> The test attempts to invalidate a block by deleting its block file and meta file.  This
happens while a datanode thread holds the files open for write.  On Windows, this causes a
locking conflict, and the test fails.
