Subject Re: [VOTE] Release Apache Hadoop 3.0.0-alpha4-RC0
Date Wed, 05 Jul 2017 15:50:57 GMT
Thanks for putting this together. I was able to build the RC, setup a
pseudo distributed cluster, and run pi and dshell tests.

There is an outstanding issue in YARN that impacts obtaining the network
details and signal handling when running with the Docker container runtime.
These will be addressed in YARN-5670. I'm not sure this is a blocker, as
docker containers can still be run, but with degraded functionality. I'm +1
if others feel this isn't a blocker.

Thanks,
-Shane
