Review request for hive and Siying Dong.
Changes
-------
That's a good point, sorry I misunderstood it originally.
Renamed estimateSampledInputSize to estimateInputSize.
Summary
-------
A query should run in local mode when block sampling is used and the sample is
small enough. The size of the sample is currently being estimated, as it is
done to estimate the number of reducers.
This addresses bug HIVE-2282.
