----------------------------------
Konstantin, if you're trying to kick a new patch build for this you now longer
move it to "Open" and back to "Patch Available". Instead, you must upload a
new patch. Or, if you have permission, you can kick
https://hudson.apache.org/hudson/job/PreCommit-HDFS-Build/ and enter the issue
number.

> When {{Datanode.makeInstance()}} cannot work with one of the directories in
> dfs.data.dir, it logs this at warn level (while losing the stack trace).
> It should include the nested exception for better troubleshooting. Then, when
> all dirs in the list fail, an exception is thrown, but this exception does
> not include the list of directories. It should list the absolute path of
> every missing/failing directory, so that whoever sees the exception can see
> where to start looking for problems: either the filesystem or the
> configuration.
