Description

Discovered while running mesos with marathon on top. If I launch a marathon task with a URI which is " http://apache.osuosl.org/mesos/0.22.1/mesos-0.22.1.tar.gz" mesos will log to stderr:

I0611 22:39:22.815636 35673 logging.cpp:177] Logging to STDERR
I0611 22:39:25.643889 35673 fetcher.cpp:214] Fetching URI ' http://apache.osuosl.org/mesos/0.22.1/mesos-0.22.1.tar.gz'
I0611 22:39:25.648111 35673 fetcher.cpp:94] Hadoop Client not available, skipping fetch with Hadoop Client
Failed to fetch:  http://apache.osuosl.org/mesos/0.22.1/mesos-0.22.1.tar.gz
Failed to synchronize with slave (it's probably exited)

It would be nice if mesos trimmed leading whitespace before doing protocol detection so that simple mistakes are just fixed.
