Review request for mesos and Timothy St. Clair.


Prefer the libcurl fetcher to the HDFS fetcher.

Bugs: MESOS-1711

Repository: mesos-git


Previously, the fetcher used a hardcoded list of schemes to determine what URIs could be fetched
by hadoop (if available). This is now changed such that we first check if hadoop can fetch
them for us and then we fallback to the os::net and then a local copy method (same as it used
to be). This allows users to fetch artifacts from arbitrary filesystems as long as hadoop
is correctly configured (in core-site.xml).

Diffs (updated)
