> 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.
