-------------------------------------
hi [~wheat9],
I have got a question when reading the patch. In
{{TestHttpFileSystem#testHttpFileSystem}}, there is
{code}
conf.set("fs.http.impl", HttpFileSystem.class.getCanonicalName());
{code}
Is this necessary? Because I did not find the key {{fs.http.impl}} used
anywhere else. Plus, the test still passed after I commented this line. If this
is not necessary, do you mind if I file a JIRA to remove this?

> 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.
