Hi James, In terms of areas of active development, there's still quite a bit to do in MapReduce and YARN. ApplicationHistoryServer (YARN-321), Rolling Restart (YARN-666), and work-preserving preemption are all in their early stages. YARN in general could also still use some polish so there are probably a decent number of JIRAs to pick up in that area. I haven't contributed very much to HDFS, so I don't have a ton of knowledge about what's going on there.
Also, I've found that a good way to start contributing is to use the software and find things about it that bother you. Hope that helps, Sandy On Mon, Jul 29, 2013 at 9:17 AM, James Carman <ja...@carmanconsulting.com>wrote: > I would like to get started contributing to Hadoop.
