----------------------------------------------------------------

The patch Falcon-47.patch is backported from Ivory.

1. Fix to support delays in feed replication
2. timeout property
3. parallel propertt

The fix for bulk-transfer via configurable frequency for replication will go in a separate
JIRA.

> Falcon Replication should support configurable delays in feed.
> By default the replication/distcp works without any delay, i.e. as soon as a feed is
scheduled, it will start replicating with the current nominal time.
> 1. We need to support usecase of delayed replication, for example, a feed can be produced
with a delay of n hours based on the process generating it, however the replication kicks
of immediately and oozie goes into waiting state and might timeout.
> 2. We need to support parallel/concurrency for feed replication by capturing it from
properties, user may want to run distcp parallelly to backfill data on another cluster.
> 3. timeout can also be set as special property.
> All these can be back-ported from Ivory release.
> 4. Need to support replication with a frequency different from the feed frequency, ex:
a feed can have hours(1) as frequency, by default a scheduled feed will distcp every hour,
however users should be able to set larger frequency like hours(6) which bulk replicates 6
hours of data in one distcp operation.
