Hey all, Work on the HDFS-1073 branch has been progressing steadily, and I believe we're coming close to the point where it can be merged. To briefly summarize the status: - NameNode and SecondaryNameNode are both fully working and have undergone some stress/fault testing in addition to a over 3000 lines worth of new unit tests. - Most of the existing unit tests have been updated, though a few more need some small tweaks (HDFS-2101) - The BackupNode and CheckpointNode are not currently working, though I am working on it locally and making good progress (HDFS-1979) - There are a few various and sundry small improvements that should probably be done before release, but I think could be done either before or after merge (eg HDFS-2104)
Given this, I am expecting that we can merge this into trunk by the end of July if not earlier, as soon as the BN/CN work is complete. If you are hoping to review the code or tests before merge time, this is your early warning! Please do so now! Thanks! -Todd P.S. I will also be giving a short talk about the motivations and current status of this project at Friday's contributor meeting, for those who are able to attend. If we're lucky, maybe even a demo! -- Todd Lipcon Software Engineer, Cloudera
