Based on the sentiment in the "[DISCUSS] 2.6.x line releases" thread, I have moved forward with some of the initial effort in creating a 2.6.5 release. I am forking this thread so we have a dedicated 2.6.5 release thread.
I have gone through the git logs and gathered a list of JIRAs that are in branch-2.7 but are missing from branch-2.6. I limited the diff to issues with a commit date after 1/26/2016. I did this because 2.6.4 was cut from branch-2.6 around that date (http://markmail.org/message/xmy7ebs6l3643o5e) and presumably issues that were committed to branch-2.7 before then were already looked at as part of 2.6.4. I have collected these issues in a spreadsheet and have given them an initial triage on whether they are candidates for a backport to 2.6.5. The spreadsheet is sorted by the status of the issues with the potential backport candidates at the top. Here is a link to the spreadsheet: https://docs.google.com/spreadsheets/d/1lfG2CYQ7W4q3olWpOCo6EBAey1WYC8hTRUemHvYPPzY/edit?usp=sharing As of now, I have identified 16 potential backport candidates. Please take a look at the list and let me know if there are any that you think should not be on the list, or ones that you think I have missed. This was just an initial high-level triage, so there could definitely be issues that are miss-labeled. As a side note: we still need to look at the pre-commit build for 2.6 and follow up with an addendum for HADOOP-12800. Thanks everyone! Chris Trezzo
