Subject Re: [VOTE] Release Apache Hadoop 3.0.0 RC0
Date Tue, 21 Nov 2017 05:46:26 GMT
Thanks for the spot Sangjin. I think this bug introduced in create-release
by HADOOP-14835. The multi-pass maven build generates these dummy client
jars during the site build since skipShade is specified.

This might be enough to cancel the RC. Thoughts?

Best,
Andrew
