Andrew Wong resolved KUDU-3071.
-------------------------------
Fix Version/s: n/a
Resolution: Won't Fix
Impala can actually leverage the split key ranges feature already because it
would (and does, following IMPALA-9792) generate tokens from its frontend.

>
> KUDU-2437 introduced the server-side ability to return "split keys" that
> logically divide a given tablet into key ranges. KUDU-2670 introduced an
> improvement in the Spark integration's KuduRDD to allow for Spark to use this
> generate smaller-scoped scan tokens that each scan a chunk of a tablet
> instead of entire tablets. This decoupled the a table's partitioning scheme
> from its read concurrency limitations.
> It'd be great if we could expose chunked-token-hydration in the C++ client so
> that Impala can begin generating these chunked tokens and then hydrating them
> into smaller scanners in its backend.
