Subject Re: [VOTE] Release Apache Hadoop 3.1.0 (RC1)
Date Tue, 03 Apr 2018 06:45:30 GMT
+1 (binding)

Thanks for putting this together, Wangda.

I deployed a 7-node hadoop cluster and:
- ran various MR jobs
- ran the same jobs with a mix of opportunistic containers via centralized
scheduling
- ran the jobs with opportunistic containers and distributed scheduling
- ran some jobs with various placement constraints.

All worked as expected.

Thanks,
Konstantinos
