Title:
  [data processing] Allow for HDFS data sources without prefix

Status in OpenStack Dashboard (Horizon):
  Fix Released

Bug description:
  Priority *wishlist*:

  This is a fix that was from the sahara-dashboard repo that came in
  after the merge was started.  It needs to be ported to the horizon
  codebase post-merge.

  Original patch:  https://review.openstack.org/#/c/92833/

  Sahara currently demands that the URL for an hdfs data source begins
  with the hdfs scheme "hdfs://". The UI enforces this restriction as
  well.

  When the hdfs scheme is specified, hadoop requires the hostname and/or
  port to be specified as well. For use of an external hdfs, of course,
  the host/port are always necessary.

  On a long running cluster, the local hdfs can be used by specifying
  the host/port of the local namenode in the path so that data can be
  read/written to the cluster hdfs, for example "hdfs://test-
  master:9000/user/hadoop/input". However, hadoop supports simpler
  absolute and relative paths to access the local hdfs without
  specification of the host and port.
