Eli Collins commented on HDFS-2802:
-----------------------------------
Let's have both on the calendar, will be useful to have multiple sessions
anyway, and Sunnyvale is pretty far for SF people. Will be useful to hear from
HBase people in the meantime. I'll post notes for people who can't make it
(happy to have remote people dial in as well).
