+1 (binding) Thanks Wangda for doing the work to produce this release. I did the following to test the release: - Built from source - Installed on 6-node pseudo cluster - Interacted with RM CLI and GUI - Tested streaming jobs - Tested yarn distributed shell jobs - Tested Max AM Resource Percent
- Tested simple inter-queue preemption - Tested priority first intra-queue preemption - Tested userlimit first intra-queue preemption Thanks,Eric Payne =========================================================== On Thursday, March 29, 2018, 11:15:51 PM CDT, Wangda Tan <wheele...@gmail.com> wrote: 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: http://people.apache.org/~wangda/hadoop-3.1.0-RC1 The RC tag in git is release-3.1.0-RC1. Last git commit SHA is 16b70619a24cdcf5d3b0fcf4b58ca77238ccbe6d The maven artifacts are available via repository.apache.org at https://repository.apache.org/content/repositories/orgapachehadoop-1090/ 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.
