Andrew Wang resolved HDFS-4360.
-------------------------------
Resolution: Won't Fix
Resolving since HDFS-RAID has been removed from Hadoop.
> multiple BlockFixer should be supported in order to improve scalability and
> reduce too much work on single BlockFixer

> Key: HDFS-4360
> URL: https://issues.apache.org/jira/browse/HDFS-4360
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: contrib/raid
> Affects Versions: 0.22.0
> Reporter: Jun Jin
> Labels: patch
> Attachments: HDFS-4360.patch
>
>
> 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
