TestEditLogRace fails on Windows
When try to call FSImage.saveFSImageInAllDirs, there's actually no directories existing. This is because the getConf() function doesn't specify creating any directories.
Remove the comment for the two lines that config directories to be created.
Not for sure why it was commented in change https://github.com/apache/hadoop/commit/3cb7ae11a839c01b8be629774874c1873f51b747 And it should also fail for Linux I guess.
