Subject Re: [VOTE] Release Apache Hadoop 2.7.0 RC0
Date Sun, 19 Apr 2015 18:07:12 GMT
Has 2.7.0 actually shipped? As in: redistributed, maven artifacts pushed out, etc. If so, it's
very much too late to do another RC.

otherwise, maybe we should recognise that 2.7.0 isn't something we could push out, simply
go straight to 2.7.1 and not worry about the 2.7.0 release -that is,  just skip the final
step of publishing.

To get that 2.7.1 out in a timely manner though, it needs to have 0 changes other than these
showstoppers; the ones which would have triggered a -1 (binding) if they showed up during
the vote
