it does apply to trunk, I just need to be in the right directory to apply the
patch :)

> Add a test to verify that userinfo data is (correctly) used to differentiate
> the entries in the FS cache, so are treated as different filesystems.
> * This is criticalk for wasb, which uses the username to identify the
> container, in a path like {{wasb:contain...@stevel.azure.net}}. This works in
> Hadoop, but SPARK-22587 shows that it may not be followed everywhere (and
> given there's no documentation, who can fault them?)
> * AbstractFileSystem.checkPath looks suspiciously like it's path validation
> just checks host, not authority. That needs a test too.
> * And we should cut the @LimitedPrivate(HDFS, Mapreduce) from
> Path.makeQualified. If MR needs it, it should be considered open to all apps
> using the Hadoop APIs. Until I looked at the code I thought it was...
