Raghu Angadi commented on HADOOP-5862:
--------------------------------------
The patch looks good. A few comments apart from Nicholas comment above.
# Need to makes sure help for command line quota commands and documentation
user guide reflect the new behaviour.
# In the Exception message, it might be better to replace "diskspace count="
with something like "diskspace consumed=". "count" might confuse users.
# Currently {{FSDirectory.updateCountForInodeWithQuota()}} warns when a
directory exceeds quota. The warning text implies it is a software error (or
corruption in the image) since it is not expected. The wording in the warning
could be changed to be less severe.

> We seem to return one generic message when either a namespace or diskspace
> quota is exceeded. We should be clearer. The error should state which
> quota is exceeded and only report statistics on the exceeded quota.
> Further namespace quota is probably not clear to most users. We should
> probably have explanatory text such as: "you have exceeded the maximum
> allowed number of files". Maybe we should even rename the quota to number of
> files quota?
> Finally, the error below would be clearer if it read:
> Quota exceeded for directory '/user/ciyaliao'.
> By not using the word "directory" it is not clear in this case if the issue
> is with a user or a directory.
> ------ AN EXAMPLE -----
> > Hi,
> >
> > I encountered an error:
> >
> > put: org.apache.hadoop.hdfs.protocol.QuotaExceededException: The quota of
> > /user/x is exceeded: namespace quota=200000 file count=200001,
> > diskspace quota=-1 diskspace=-44221467605496
> >
> > It apparently complains that dfs quota is exceeded. But I only use around
> > 200GB disk space. From the error message, what kind of quota did I actually
> > exceed? How do I check my usage of this type of quota?
