+1 (binding)
- checked signatures and hashes
- built from source without skipping tests (without Hadoop, Scala 2.12)
- no new dependencies were added since 1.8.0
- ran the end-to-end tests locally once, and in a loop specifically for
Kafka tests (to cover FLINK-11987)
- announcement PR for website looks good!
Cheers,
Gordon

Re: [VOTE] Release 1.8.1, release candidate #1
Posted by Hequn Cheng <ch...@gmail.com>.
Hi Jincheng,
Thanks a lot for the release which contains so many fixes!
I have done the following checks:
Local Tests
- Built from source archive successfully.
- Signatures and hash are correct.
- All artifacts have been deployed to the maven central repository.
- Run WordCount(batch&streaming) on Local cluster successfully.
Cluster Tests
Cluster environment: 7 nodes, jm 1024m, tm 4096m
Testing Jobs: WordCount(batch&streaming), DataStreamAllroundTestProgram
- Read and write hdfs file successfully.
- Run jobs on YARN(with or without session) successfully
- Job failover and recovery successfully
PR review
- Left a minor comment. But I think it is not a blocker, we can just update
the PR directly.
To sum up, I have not spotted any blockers, so +1(non-binding) from my
side.
Best, Hequn
