Dennis Huo commented on HDFS-14147: ----------------------------------- The branch-2.8 confusion might be because I had started with some prototype branch-2.8 patches in HDFS-13056 but I never got around to cleaning it up and refactoring for actually committing into 2.8. Yan's dependency analysis looks good to me and should allow a clean merge into 2.9, 2.8, and 2.7. > Backport of HDFS-13056 to the 2.9 branch > ---------------------------------------- > > Key: HDFS-14147 > URL: https://issues.apache.org/jira/browse/HDFS-14147 > Project: Hadoop HDFS > Issue Type: New Feature > Components: datanode, distcp, hdfs > Affects Versions: 2.9.0, 2.9.1, 2.9.2 > Reporter: Yan > Priority: Major > Attachments: HDFS-14147-branch-2.9.v1.patch, HDFS-14147.pdf > > > HDFS-13056, Expose file-level composite CRCs in HDFS which are comparable > across different instances/layouts, is a significant feature for storage > agnostic CRC comparisons between HDFS and cloud object stores such as S3 and > GCS. With the extensively installed base of Hadoop 2, it should make a lot of > sense to have the feature in Hadoop 2. > The plan is to start with the backporting to 2.9, followed by 2.8 and 2.7 in > that order. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
