Here where the things that stuck out to me:
- Hortonworks are getting vmware to get namenode redundant
- EMC launched their fork off of Apache hadoop with increased integration with Greenplum via Pivotal HD and Hawk.
- Intel wants you to use more computers and have done pretty much what horton did. Get your support from us (intel). And buy more hardware….
- Riak was there (sounds cool).
- Lots of buzz about Storm
I also enjoyed http://www.zoomdata.com/ (really cool visualization of data).
All and all a great move forward for hadoop.
