I see that webhdfs does not support directory size. In HDFS, I can use
hdfs dfs -du -s -h /my/directory
Is there a way to derive this from webHDFS? I need to do this programmatically, not by viewing the page.
Get directory size from WebHDFS?

I think WebHDFS's GETCONTENTSUMMARY can provide you the information. More information here: http://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-hdfs/WebHDFS.html#Get_Content_Summary_of_a_Directory
Here is the schema for GETCONTENTSUMMARY: http://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-hdfs/WebHDFS.html#ContentSummary_JSON_Schema
You'll see that it has the filed "spaceConsumed" which is the disk space consumed.
