Subject [jira] [Commented] (HDFS-2802) Support for RW/RO snapshots in HDFS
Date Mon, 29 Oct 2012 23:48:16 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2802?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13486513#comment-13486513

Eli Collins commented on HDFS-2802:

Will schedule a design review meeting to go over the requirements and design in detail with
the folks who are interested. Especially to get feedback from other Hadoop projects. This
meeting will be in the week of Oct 29, post Hadoop World.

I went ahead and scheduled this, will host at the Cloudera office in Palo Alto. Since we've
got interested people from Sunnyvale to SF, Palo Alto seems like a good middle ground. Also,
I've confirmed with some HBase people that they will be able to attend so we can feedback
from other projects. Here's the meetup page, I'll add Webex notes for remote people soon.
Also, I'll take minutes and post them back here.

> Snapshots are point in time images of parts of the filesystem or the entire filesystem.
Snapshots can be a read-only or a read-write point in time copy of the filesystem. There are
several use cases for snapshots in HDFS. I will post a detailed write-up soon with with more
