             Summary: Access HDFS through a proxy and natively
                 Key: HDFS-13894
                 URL: https://issues.apache.org/jira/browse/HDFS-13894
             Project: Hadoop HDFS
          Issue Type: New Feature
            Reporter: Íñigo Goiri
            Assignee: Íñigo Goiri


HDFS deployments are usually behind a firewall where one can access the 
Namenode but not the Datanodes. To mitigate this situation there are proxies 
that catch the DN requests (e.g., HttpFS). However, if a user submits a job 
using the HttpFS endpoint, all the workers will use such endpoint which will 
usually be a bottleneck.

We should create a new filesystem that supports accessing both:
* HttpFS for submission from outside the firewal
* HDFS from within the cluster
