Re: [VOTE] Release Apache Arrow 0.16.0 - RC1
Hi, Sorry for my late summary. I verified RC1 and have been fixed some problems. Here are remained problems I found: * "yum install"/"dnf install" don't work. It seems that Yum repository's metadata is broken. It may be a our new binary upload script problem. The script may have a retry related problem. * "dev/release/verify-release-candidate.sh wheels 0.16.0 1" doesn't work. See the following log for details. I think that this is a verify script problem but I don't know how to fix it. It may be a Conda related problem. https://github.com/apache/arrow/blob/master/dev/release/verify-release-candidate.sh#L613 + conda install -y --file /home/kou/work/cpp/arrow.kou/ci/conda_env_python.yml pandas + '[' 5 -lt 1 ']' + local cmd=install + shift + case "$cmd" in + OLDPATH=/tmp/arrow-0.16.0.j9Uct/test-miniconda/envs/_verify_wheel-2.7mu/bin:/tmp/arrow-0.16.0.j9Uct/test-miniconda/condabin:/home/kou/work/go/bin:/bin:/home/kou/local/bin:/home/kou/.config/composer/vendor/bin:/var/lib/gems/2.5.0/bin:/usr/local/bin:/usr/bin:/usr/games + __add_sys_prefix_to_path + '[' -n '' ']' ++ dirname /tmp/arrow-0.16.0.j9Uct/test-miniconda/bin/conda + SYSP=/tmp/arrow-0.16.0.j9Uct/test-miniconda/bin ++ dirname /tmp/arrow-0.16.0.j9Uct/test-miniconda/bin + SYSP=/tmp/arrow-0.16.0.j9Uct/test-miniconda + '[' -n '' ']' + PATH=/tmp/arrow-0.16.0.j9Uct/test-miniconda/bin:/tmp/arrow-0.16.0.j9Uct/test-miniconda/envs/_verify_wheel-2.7mu/bin:/tmp/arrow-0.16.0.j9Uct/test-miniconda/condabin:/home/kou/work/go/bin:/bin:/home/kou/local/bin:/home/kou/.config/composer/vendor/bin:/var/lib/gems/2.5.0/bin:/usr/local/bin:/usr/bin:/usr/games + export PATH + /tmp/arrow-0.16.0.j9Uct/test-miniconda/bin/conda install -y --file /home/kou/work/cpp/arrow.kou/ci/conda_env_python.yml pandas Collecting package metadata (current_repodata.json): ...working... done Solving environment: ...working... failed with initial frozen solve.

Re: [VOTE] Release Apache Arrow 0.16.0 - RC1
An update on Spark integration tests: the new error looks to be a regression so I made https://issues.apache.org/jira/browse/ARROW-7723 and marked as a blocker. It's possible to work around this bug, so I wouldn't call it a hard blocker if we need to proceed with the release.

Re: [VOTE] Release Apache Arrow 0.16.0 - RC1
The place where the segfault is triggered in the R nightlies is a couple of tests after the one I added in that patch. If that patch is causing the segfaults, we can skip the new test ( https://github.com/apache/arrow/blob/master/r/tests/testthat/test-parquet.R#L125) and investigate later. The patch is exercising previously existing codepaths that were not tested, so I don't think that identifying and fixing the segfault should be release blocking (though we should clearly fix it).

Re: [VOTE] Release Apache Arrow 0.16.0 - RC1
The Flight leak should be unrelated to that commit, the failing test already existed before - it's a flaky test https://issues.apache.org/jira/browse/ARROW-7721. I'm hoping to look at the issue this week but we might just want to disable the test for now.

Re: [VOTE] Release Apache Arrow 0.16.0 - RC1
Hi, - The fuzzit builds has been disabled by Neal on the current master. - Created a PR to resolve occasionally failing python dataset tests [1] - Merged the fix for C# timezone error [2] - Merged various fixes for the release scripts. - The nightly Gandiva OS X build is still failing, but because of a travis deployment timeout, which shouldn't block the release. We still have failing tests: - failing Spark integration test - failing nightly R builds (see the 2020-01-29 nightly report) - master reports a Java flight memory leak Spark: Joris created a fix for the immediate issue [3], but now we have a different spark test error, see the discussion in the PR [3]. I put up a PR [6] to check the regressions 0.16 arrow release would introduce for spark interoperability, and it turns out that arrow 0.15.1 is not compatible with neither spark 2.4.4 nor spark 2.4.5-rc1, so 0.16 arrow release could only be compatible with spark 3.0 or spark master which we have tests for. So I'm a bit confused how to interpret arrow backward compatibility with Spark, thus what should and what should not block the release. Either way we'll need to fix the remaining spark issues and add nightly spark integration tests for both the next spark release and spark master. R: There is the same segfault in each R nightly builds [4]. There was a single change [5] which could introduce the regression compared to the previous builds. I've tried to reproduce the builds using docker-compose, but locally 3.6-bionic has passed for me. I'm trying to wipe my local cache and rerun to see whether I can reproduce it. Java/Flight leak: The current master reports memory leak [6] which I guess is surfaced by change [7] If we manage to fix the issues above today than I can cut RC2 tomorrow.

Re: [VOTE] Release Apache Arrow 0.16.0 - RC1
The nightly Spark integration was failing because a test was renamed recently in master. Once I fixed that and ran it again, this surfaced. I remember it passed after the `split_blocks` change not too long ago, so all this is pretty recent.

Re: [VOTE] Release Apache Arrow 0.16.0 - RC1
Hi Gawain -- since PARQUET issues are attached to a different project and fix version these have to be extracted from the git changelog. We can alter our scripts to scrape these commits from the git log output.
