Surendra Singh Lilhore commented on HDFS-253:
---------------------------------------------
Little change in above implementation.
1. We already have {{Count}} command for getting the quota information. Same I
added one new command {{listCount}} to get the content summary from HDFS.
{code}
./hdfd dfs -listCount [-q [-n | -s] ] [-h] [-r] [-v] <path>
List the directories with the quotas, directories, files and bytes count under
the paths
The -q option displays quotas.
The -n option displays only name quota. It must be used with -q option.
The -s option displays only space quota. It must be used with -q option.
The -h option shows file sizes in human readable format.
The -v option displays a header line.
{code}
2. Added one new API {{listContentSummary()}} in ClientProtocol.java for
retrieving {{ContentSummary}} from namenode , It will return
DirectoriesContentSummary.
3. Added one new API in FileSystem.java, it will return
RemoteIterator<ContentSummary>.
{code}
public RemoteIterator<ContentSummary> listContentSummary(Path path,
boolean recurcive
{code}

> Currently the only way to view quota information on an HDFS is via dfs -count
> -q, which is fine when an admin is examining a specific directory for quota
> status.
> It would also be good to do full HDFS quota audits, by pulling all HDFS
> quotas currently set on the system. This is especially important when trying
> to do capacity management ("OK, how much quota have we allotted so far?"). I
> think the only way to do this now is via lsr | count -q, which is pretty
> cumbersome.
