Subject Re: [Virtual MEETUP]: Migration to Hadoop 3
Date Thu, 27 Aug 2020 06:24:12 GMT
Hi folks

great to see the participation and thanks all for joining!

@Wei-Chiu Chuang <weichiu@apache.org> 3.1 is one of the stable line along
with 3.2
As we are moving to a stable 3.3, we should start to visit the fate of 3.1
by end of this year and early next year.

Thanks
Sunil
