Subject Re: Hadoop 3.1.0 release discussion
Date Sat, 27 Jan 2018 01:21:11 GMT
Hi All,

Just a reminder about feature freeze date.

Feature freeze date for 3.1.0 release is Jan 30 PST (about 4 days from
today), If you've any features which live in a branch and targeted to
3.1.0, please reply this email thread. Ideally, we should finish branch
merging before feature freeze date.

Here's an updated 3.1.0 feature status:

1. Merged features:
* (Sunil) YARN-5881: Support absolute value in CapacityScheduler.
* (Wangda) YARN-6223: GPU support on YARN. Features in trunk and works
end-to-end.
* (Jian) YARN-5079,YARN-4793,YARN-4757,YARN-6419 YARN native services.
* (Steve Loughran): HADOOP-13786: S3Guard committer for zero-rename commits.
* (Suma): YARN-7117: Capacity Scheduler: Support Auto Creation of Leaf
Queues While Doing Queue Mapping.
* (Chris Douglas) HDFS-9806: HDFS Tiered Storage.
* (Zhankun) YARN-5983: FPGA support. Majority implementations completed and
merged to trunk. Except for UI/documentation.

2. Features close to finish:
* (Uma) HDFS-10285: HDFS SPS. There're two remaining
blockers: HDFS-12995/HDFS-13050. @Uma could you update what's the ETA of
the two JIRAs?
* (Arun Suresh / Kostas / Wangda). YARN-6592: New SchedulingRequest and
anti-affinity support. (Voting thread started).

3. Tentative features:
* (Arun Suresh). YARN-5972: Support pausing/freezing opportunistic
containers. Only one pending patch. Plan to finish before Jan 7th.
* (Haibo Chen). YARN-1011: Resource overcommitment. Looks challenging to be
done before Jan 2018.
* (Anu): HDFS-7240: Ozone. Given the discussion on HDFS-7240. Looks
challenging to be done before Jan 2018.
* (Varun V) YARN-5673: container-executor write. Given security refactoring
of c-e (YARN-6623) is already landed, IMHO other stuff may be moved to 3.2.

Thanks,
Wangda
