Hi folks,

Thanks to the many who helped with this release since Dec 2017 [1]. We've
created RC1 for Apache Hadoop 3.1.0. The artifacts are available here:


The RC tag in git is release-3.1.0-RC1. Last git commit SHA is

The maven artifacts are available via repository.apache.org at
This vote will run 5 days, ending on Apr 3 at 11:59 pm Pacific.

3.1.0 contains 766 [2] fixed JIRA issues since 3.0.0. Notable additions
include the first class GPU/FPGA support on YARN, Native services, Support
rich placement constraints in YARN, S3-related enhancements, allow HDFS
block replicas to be provided by an external storage system, etc.

For 3.1.0 RC0 vote discussion, please see [3].

We’d like to use this as a starting release for 3.1.x [1], depending on how
it goes, get it stabilized and potentially use a 3.1.1 in several weeks as
the stable release.

We have done testing with a pseudo cluster:
- Ran distributed job.
- GPU scheduling/isolation.
- Placement constraints (intra-application anti-affinity) by using
distributed shell.

My +1 to start.


[2] project in (YARN, HADOOP, MAPREDUCE, HDFS) AND fixVersion in (3.1.0)
AND fixVersion not in (3.0.0, 3.0.0-beta1) AND status = Resolved ORDER BY
fixVersion ASC
