Aaron Fabbri commented on HADOOP-13786: --------------------------------------- I'll try to get you some useful code reviews soon.. Been busy with releases. Wow there is a lot of code to catch up on here. > Add S3Guard committer for zero-rename commits to consistent S3 endpoints > ------------------------------------------------------------------------ > > Key: HADOOP-13786 > URL: https://issues.apache.org/jira/browse/HADOOP-13786 > Project: Hadoop Common > Issue Type: New Feature > Components: fs/s3 > Affects Versions: HADOOP-13345 > Reporter: Steve Loughran > Assignee: Steve Loughran > Attachments: HADOOP-13786-HADOOP-13345-001.patch, > HADOOP-13786-HADOOP-13345-002.patch, HADOOP-13786-HADOOP-13345-003.patch, > HADOOP-13786-HADOOP-13345-004.patch, HADOOP-13786-HADOOP-13345-005.patch, > HADOOP-13786-HADOOP-13345-006.patch, HADOOP-13786-HADOOP-13345-006.patch, > HADOOP-13786-HADOOP-13345-007.patch, HADOOP-13786-HADOOP-13345-009.patch, > HADOOP-13786-HADOOP-13345-010.patch, HADOOP-13786-HADOOP-13345-011.patch, > HADOOP-13786-HADOOP-13345-012.patch, HADOOP-13786-HADOOP-13345-013.patch, > HADOOP-13786-HADOOP-13345-015.patch, HADOOP-13786-HADOOP-13345-016.patch, > HADOOP-13786-HADOOP-13345-017.patch, HADOOP-13786-HADOOP-13345-018.patch, > s3committer-master.zip > > > A goal of this code is "support O(1) commits to S3 repositories in the > presence of failures". Implement it, including whatever is needed to > demonstrate the correctness of the algorithm. (that is, assuming that s3guard > provides a consistent view of the presence/absence of blobs, show that we can > commit directly). > I consider ourselves free to expose the blobstore-ness of the s3 output > streams (ie. not visible until the close()), if we need to use that to allow > us to abort commit operations. -- This message was sent by Atlassian JIRA (v6.3.15#6346) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
