Todd Lipcon updated HDFS-1521: ------------------------------ Attachment: hdfs-1521.txt I took a swing through Ivan's latest patch and looks good to me. I fixed up one javadoc error and added a new comment in one bit of code that needed some clarification. Aside from that, this patch is identical to Ivan's. +1 from me - Konstantin, would you mind taking one last look before we commit this? > Persist transaction ID on disk between NN restarts > -------------------------------------------------- > > Key: HDFS-1521 > URL: https://issues.apache.org/jira/browse/HDFS-1521 > Project: Hadoop HDFS > Issue Type: Sub-task > Components: name-node > Affects Versions: 0.22.0 > Reporter: Todd Lipcon > Assignee: Todd Lipcon > Attachments: HDFS-1521.diff, HDFS-1521.diff, HDFS-1521.diff, > hdfs-1521.3.txt, hdfs-1521.4.txt, hdfs-1521.5.txt, hdfs-1521.txt, > hdfs-1521.txt, hdfs-1521.txt > > > For HDFS-1073 and other future work, we'd like to have the concept of a > transaction ID that is persisted on disk with the image/edits.
