Hi all, Based on the feedback from previous email threads and JIRAs, we are in good time for releasing 2.6.3!
Things Done/TODO: + Branch -- Based on branch-2.6, which has been open to 2.6.3 commits for a while, I already branch out branch-2.6.3 today. -- New commits coming as fix to 2.6.3 need to explicitly cherry-pick to branch-2.6.3 as well as branch-2.6. + Patches -- 2.6.3 already has 31 fixes as list of [1] shows. -- The list of open tickets [2] on 2.6.3 is relative small (3 for now) as we already move non-blocker / non-critical ones out to 2.6.4. I'll keep triaging and see what we can get in within a week or so. + Release -- Given the open ticket list is relative short and all of them are patch available, I plan to start RC process for voting early next week with leaving aside some buffer time. Thoughts? Appreciate any help in moving forward open tickets [2]. Thanks, Junping [1] 2.6.3 Fixed Tickets: http://s.apache.org/Ylq [2] 2.6.3 Tickets: http://s.apache.org/9A7 ________________________________ From: Junping Du Sent: Tuesday, December 01, 2015 12:26 PM To: Vinod Kumar Vavilapalli Cc: Sangjin Lee; mapreduce-...@hadoop.apache.org; yarn-...@hadoop.apache.org; Hadoop Common; hdfs-...@hadoop.apache.org; Haohui Mai; Chris Trezzo; junping...@apache.org Subject: Re: continuing releases on Apache Hadoop 2.6.x Thanks Vinod! I went through all 31 fixes (Common: 8, HDFS: 6, MAPREDUCE: 8, YARN: 9) landed on branch-2.6 now, and all outstanding patches (>=5KB) are listed below and they are all bug fix. Haven't found any high risky patches so far but I noticed we have 3 significant fixes (MAPREDUCE-5948, MAPREDUCE-6481 and MAPREDUCE-6549) for LineRecordReader. Among them, MAPREDUCE-5948 and MAPREDUCE-6481 are completed fixes and we will ship them in 2.7.2, so I think there is no risk with them. MAPREDUCE-6549, together with an open JIRA: MAPREDUCE-6558, sounds like fix the same issue for uncompressed/compressed input file. I already ping the JIRA owners to get suggestions on if we could release MAPREDUCE-6549 independently or together with MAPREDUCE-6558 in next release. I already pinged all owners for open JIRAs that targeted for 2.6.3 to move it to 2.6.4. Based on the feedback from JIRAs (and voices here too), I will create branch-2.6.3 in next 1 day or 2. Thanks! List of Outstanding Patches: HADOOP-10134 [JDK8] Fix Javadoc errors caused by incorrect or illegal tags in doc comments. (apurtell via stevel) 38K HDFS-9289.

LineRecordReader may give incomplete record and wrong position/key information for uncompressed input sometimes. (Zhihai Xu via jlowe) 19K MAPREDUCE-6549. multibyte delimiters with LineRecordReader cause duplicate records (wilfreds via rkanter) 31K YARN-2859.
