    Description

      We current have hftp for accessing HDFS over HTTP. However, hftp is a read-only FileSystem and does not provide "write" accesses.

      In HDFS-2284, we propose to have WebHDFS for providing a complete FileSystem implementation for accessing HDFS over HTTP. The is the umbrella JIRA for the tasks.
