There is a file lock on this file that causes the issue, which might be hiding another issue even on other platforms.

In #10680, we added
fysncon dir to maintain crash consistency. But, it looks like Windows OS doesn't supportfsyncon directory. The same issues also happen on LUCENE and HDFS projects. And the way they fix it is pretty much the same: to skip fsync directory on Windows OS. Here are the patches for both LUCENE-5588 and HDFS-13586.I followed their way to fix this issue. No tests added since it's just an OS check added, no logic change.
