Subject [jira] [Created] (HDFS-13894) Access HDFS through a proxy and natively
Date Tue, 04 Sep 2018 23:34:00 GMT
Íñigo Goiri created HDFS-13894:

             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
