             Summary: Implement a FileSystem that reads from HTTP
                 Key: YARN-6556
                 URL: https://issues.apache.org/jira/browse/YARN-6556
             Project: Hadoop YARN
          Issue Type: Improvement
            Reporter: Haohui Mai
            Assignee: Haohui Mai


We have a use case where YARN applications would like to localize resources from Artifactory. Putting the resources on HDFS itself might not be ideal as we would like to leverage Artifactory to manage different versions of the resources.

It would be nice to have something like {{HttpFileSystem}} that implements the Hadoop filesystem API and reads from a HTTP endpoint.

Note that Samza has implemented the proposal by themselves:

https://github.com/apache/samza/blob/master/samza-yarn/src/main/scala/org/apache/samza/util/hadoop/HttpFileSystem.scala

The downside of this approach is that it requires the YARN cluster to put the Samza jar into the classpath for each NM.

It would be much nicer for Hadoop to have this feature built-in.
