Eli Collins commented on HDFS-2802:
-----------------------------------
Hey Suresh,
This isn't the one and only discussion on snapshots, a lot of us plan to attend
the following one as well. It's OK to have multiple discussions. A bunch of
people are going to be around and discussing things on Thursday anyway, so I
thought it better to open up the discussion to more people in the community.
I'm sorry that you'll be out of town, I've setup a dial in and would love it if
you and others that are out could attend. I'll post minutes here so that people
who can not attend can see and participate.
