Subject [jira] [Commented] (ACCUMULO-1419) Make hadoop2 the default
Date Fri, 24 May 2013 01:22:20 GMT

Josh Elser commented on ACCUMULO-1419:
--------------------------------------

I understand that. My point was that I feel that we shouldn't change our default until there
is a 2.0 release which is classified by the community as more than "alpha". Assuming beta
releases happen, that's fine. Just voicing my concern that until such a hadoop release happen,
I don't think we should change our default.

As for the data loss point, there is also the possibility that hadoop2 will cause data loss
that hadoop1 did not, but that's just speculation. It's always possible that hadoop2 introduces
new issues too.

It's perfectly fine to hope for making hadoop2 the default in 1.6.0; I just don't want us
to jump the gun.

> This is a proposed feature for 1.6.
> There's two ways we could do this:
>  # Continue to support both hadoop1 and hadoop2, but switch the profiles, so hadoop2
is the default, and this is what we use to build binary artifacts for release voting.
>  # Make hadoop2 required and get rid of the dependency profiles.
