Subject [jira] [Commented] (HDFS-1623) High Availability Framework for HDFS NN
Date Thu, 23 Feb 2012 14:44:53 GMT

    [ https://issues.apache.org/jira/browse/HDFS-1623?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13214778#comment-13214778
] 

Aaron T. Myers commented on HDFS-1623:
--------------------------------------

bq. Here is a patch that merges current HDFS-1623 branch to trunk.

Thanks a lot, Jitendra. This might make it easier for some to review the merge.

For anyone else who wants to review it, note that we've been merging from trunk -> HA branch
almost daily, so just looking at a diff between trunk and the HA branch should mostly highlight
the salient changes for HA. I also strongly recommend that any reviewers who are just now
looking at the branch take a look at [the testing plan document attached to this JIRA by Todd|https://issues.apache.org/jira/secure/attachment/12514080/ha-testplan.pdf],
which discusses which areas of the code have the most changes in section 1.5.
