Subject Re: [DISCUSS] Drop legacy hadoop support at the 2.0 release
Date Wed, 19 Oct 2016 05:18:09 GMT
we had not decided yet AFAIK. a big concern was the lack of
maintenance releases on more recent Hadoop versions and the perception
that 2.4 and 2.5 were the last big stable release lines.

2.6 and 2.7 have both gotten a few maintenance releases now, so maybe
this isn't a concern any more?
