> I suggest we should move to Hadoop 0.21 for the next release. It is the current release, soon to be superseded by 0.22. It matches more closely what CDH3/4 users use. It has bug fixes, and crucially some features that make joins much less painful.
> The drawback is that EMR does not yet support it. I still suggest we forge ahead as one imagines it will be supported by the time we release 0.6.
