My only concern would be that updating our listed Hadoop dependency version would make it easy for someone to accidentally rely on a Hadoop API call that wasn't in earlier versions, which would then make it harder for an interested person to patch their 1.y version to use the earlier Hadoop version. HBase checks compilation against different hadoop versions in their precommit checks. We could add something like that to our nightly builds maybe? Now that we're discussing it, I can't actually remember if we ever documented what version(s) of Hadoop we expect to work with. So maybe updating to the latest minor release of 2.y on each Accumulo 1.y minor release can just be our new thing. -- busbey
