Chris Nauroth updated HDFS-4752:
--------------------------------
Attachment: HDFS-4752.1.patch
I'm attaching a patch that overrides the datanode behavior to open the block
and meta files with share delete permission via a JNI call on Windows.
This is a bit messy, so I'm curious to get feedback. We've solved similar
problems in the past by stopping the daemon that holds the file opened before
corrupting the underlying files, but in this case, stopping the daemon would
ruin the intent of the test. I also didn't think it was correct in general to
use share delete here, so I triggered the logic from a new config flag that is
only set to true by this test.
I verified that the test passes on Mac and Windows.

> 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.
