Subject [jira] [Commented] (HDFS-2802) Support for RW/RO snapshots in HDFS
Date Wed, 07 Nov 2012 01:44:15 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2802?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13492046#comment-13492046

Aaron T. Myers commented on HDFS-2802:
--------------------------------------

Just FYI - I've set up a nighly Jenkins build of the HDFS-2802 branch here: https://builds.apache.org/view/G-L/view/Hadoop/job/Hadoop-Hdfs-Snapshots-Branch-build/

Currently I'm the only one who gets emailed about it. If you're a committer or the like you
can just add your email to that job configuration if you want to get emails with the restuls.
If you're not, let me or someone else with access know and we can add your email to the list
of who gets emailed by that job. Last night a bunch of tests failed because of HDFS-4158,
but if someone can review that soon I'll check it in tonight and hopefully get a better test
run.

> 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
information.
