Subject Re: [DISCUSS] Looking to Apache Hadoop 3.1 release
Date Fri, 08 Sep 2017 01:03:05 GMT
Thanks for starting this thread, Wangda!

+1 for establishing a faster cadence now itself.

One word of caution though. The same I expressed while we were trying to do both 2.8 and 3.0
releases at the same time. Please try avoiding concurrent releases and splitting community
bandwidth - it's not that we cannot do multiple releases in parallel, it's mainly that we
will not be able to give our best on both.

Thanks
+Vinod
