> If a quota violation is detected while loading an image, the NameNode logs scary error messages indicating a bug. However the quota violation state is very easy to get into e.g.
> # Copy a 2MB file to a directory.
> # Set a disk space quota of 1MB on the directory. We are in quota violation state now.
> We should reword the error messages, ideally making them warnings and suggesting the administrator needs to fix the quotas:
> Relevant code:
> {code}
>         LOG.error("BUG: Diskspace quota violation in image for "
>             + dir.getFullPathName()
>             + " quota = " + dsQuota + " < consumed = " + diskspace);
> ...
>           LOG.error("BUG Disk quota by storage type violation in image for "
>               + dir.getFullPathName()
>               + " type = " + t.toString() + " quota = "
>               + typeQuota + " < consumed " + typeSpace);
> {code}
