Jeff Hammerbacher commented on HIVE-1541:
-----------------------------------------
In particular, it would be nice to avoid the startup overhead of Hadoop
MapReduce with this backend.
> More general dataflow execution backend

> Key: HIVE-1541
> URL: https://issues.apache.org/jira/browse/HIVE-1541
> Project: Hadoop Hive
> Issue Type: New Feature
> Reporter: Jeff Hammerbacher
>
> With the recent open source release of Mesos (http://github.com/mesos/mesos),
> experimentation at the query execution layer has become more feasible.
> Inspired by more general-purpose dataflow systems like Volcano, Dryad, and
> Dremel, it would be interesting to explore a more general-purpose dataflow
> execution system for Hive queries. One potential backend is the Hyracks
> project from UCI: http://code.google.com/p/hyracks.
