Matei Zaharia commented on SPARK-889:
-------------------------------------
This is a really old JIRA and actually I wouldn't implement this now.
HTTPBroadcast works as well as DFS did, and TorrentBroadcast is even better. We
just need to make TorrentBroadcast the default -- would be great if you can
spend some time testing that.

> DFS broadcast was a simple way to get better-than-single-master performance
> for broadcast, so we should add it back for people who have HDFS.
