James Cunningham created MESOS-4304:
---------------------------------------
Summary: hdfs operations fail due to prepended / on path for
non-hdfs hadoop clients.
Key: MESOS-4304
URL: https://issues.apache.org/jira/browse/MESOS-4304
Project: Mesos
Issue Type: Bug
Components: fetcher
Affects Versions: 0.26.0
Reporter: James Cunningham
This bug was resolved for the hdfs protocol for MESOS-3602 but since the
process checks for the "hdfs" protocol at the beginning of the URI, the fix
does not extend itself to non-hdfs hadoop clients.

{code}
After a brief chat with [~jieyu], it was recommended to fix the current hdfs
client code because the new hadoop fetcher plugin is slated to use it.
