Subject [jira] [Commented] (ACCUMULO-1402) Hadoop2 maven artifacts
Date Wed, 15 May 2013 21:27:17 GMT


Christopher Tubbs commented on ACCUMULO-1402:

{quote}If we can only provide binaries for one hadoop version, should we consider making it
version 2 ... ?{quote}

I have two concerns about that:

 # I'm uncomfortable getting behind a default version for our binary artifacts that don't
work against any hadoop release marked as "stable". (I can get over this)
 # It wasn't a planned feature to make Hadoop2 the default. I'd be more accepting of this
proposal if it were a 1.6 feature. (I can also get over this)

I think a better alternative is to keep binary support for only Hadoop1, for the 1.5 release
artifacts, and vote separately on a secondary binary tarball release built from the 1.5 tag
for Hadoop2 support... just so we can get 1.5 out the door. Then, make a ticket for dropping
Hadoop1 support entirely for Hadoop2 in 1.6, due to ACCUMULO-1364.

> jars need to be compiled separately for hadoop1 vs. hadoop2. Both versions are used in
the wild, and will cause a lot of work helping users who do not realize this mistake when
they add a maven dependency and expect the one from central to work for their hadoop 2 installation.
We should package a separate hadoop2alpha set of jars to release to central for people working
against hadoop2 to use.
