--------------------------------------------

We could extend fsck or web ui to show directories in this state.
{quote}
I feel, logging the warn message is better( Or even we can delete this log
).Since Quota Viloation on one or more directories does not affect the the
functioning of HDFS in any way..
Keeping in fsck or web will be clumsy if there are so many directories meet
conditions ( even safe mode or missing blocks etc..present same time which may
not be require)..
Please correct me If I am wrong...

> Key: HDFS-7757
> URL: https://issues.apache.org/jira/browse/HDFS-7757
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: namenode
> Affects Versions: 2.6.0
> Reporter: Arpit Agarwal
> Assignee: Brahma Reddy Battula
>
> 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}
