    Could be setCause

<http://review.cloudera.org/r/816/#comment4957>

    Agree, subpackage would be a pain but Javadoc can make it explicit for sure.

<http://review.cloudera.org/r/816/#comment4955>

    Only one instance of a given Coprocessor class can be bound to a region at a time.



src/main/java/org/apache/hadoop/hbase/client/ExecResult.java
<http://review.cloudera.org/r/816/#comment4958>

    This is pretty generic but currently has no other use, correct.



src/main/java/org/apache/hadoop/hbase/client/Scan.java
<http://review.cloudera.org/r/816/#comment4959>

    We should be getting rid of RowRange, right?

<http://review.cloudera.org/r/816/#comment4960>

    Good, likewise for exec() as below.

> "High-level call interface for clients. Unlike RPC, calls addressed to rows or ranges
of rows. Coprocessor client library resolves to actual locations. Calls across multiple rows
automatically split into multiple parallelized RPCs"
> Generic multicall RPC facility which incorporates this and multiget/multiput/multidelete
and parallel scanners.
> Group and batch RPCs by region server. Track and retry outstanding RPCs. Ride over region
relocations. 
> Support addressing by explicit region identifier or by row key or row key range. 
> Include a facility for merging results client side.
