---------------------------------------------
Reviewed the failed junit test, I don't think it's related, as it touched
different parts of the code and it's passing on my local build:

> Components: httpfs
> Affects Versions: 3.0.0-alpha3
> Reporter: Wellington Chevreuil

> Currently, HttpFS is lacking implementation for SNAPSHOT related methods from
> WebHDFS REST interface as defined by WebHDFS documentation [WebHDFS
> documentation|https://archive.cloudera.com/cdh5/cdh/5/hadoop/hadoop-project-dist/hadoop-hdfs/WebHDFS.html#Snapshot_Operations]
> I would like to work on this implementation, following the existing design
> approach already implemented by other WebHDFS methods on current HttpFS
> project, so I'll be proposing an initial patch soon for reviews.
