> current implementation can only run single BlockFixer since the fsck (in
> RaidDFSUtil.getCorruptFiles) only check the whole DFS file system. multiple
> BlockFixer will do the same thing and try to fix same file if multiple
> BlockFixer launched.
> the change/fix will be mainly in BlockFixer.java and
> RaidDFSUtil.getCorruptFile(), to enable fsck to check the different paths
> defined in separated Raid.xml for single RaidNode/BlockFixer
