> With Roman, am trying to set up a bigtop ci of hbase 0.95 only we fail to
> compile. It is the exotic generics that are going on over in
> AggregateClient. Here is how we fail:

> I cannot reproduce locally but googling, I see that above is pretty common
> complaint when you move between compilers. Various are the recommendations
> for fix but none definitive. The easiest is dumbing down the generics which
> I tried but it only caused issues in other coprocessors.
> If clues on how to fix this, I'm all ears. Would like to get this bigtop ci
> build running. Its cool.
