> the max length of a row has to fit into a signed short. That is 32k.  The constant is incorrect, but in the depths of KeyValue it does the right thing:
>     if (rlength > Short.MAX_VALUE) {
>       throw new IllegalArgumentException("Row > " + Short.MAX_VALUE);
>     }
> so your Put wont fail and instead it will fail in the KeyValue constructor.  So far only that 1 line in Put uses this constant, but we should have a correct value here.
