> The tests change the block length to corrupt the data block. If the block file is opened by the datanode then the test can concurrently modify it on Linux but such concurrent modification is not allowed by the default permissions on Windows. Since this is more of a test issue, the fix would be to have the tests make sure that the block is not open concurrently.
