Sketch Adaptors for Hive

Depends on sketches-core.

To use Hive UDFs, you should do the following:

Register the JAR file with Hive:

hive> add jar sketches-hive-0.1.0-incDeps.jar

Register UDF functions with Hive:

hive> create temporary function estimate as 'com.yahoo.sketches.hive.theta.EstimateSketchUDF';
hive> create temporary function dataToSketch as 'com.yahoo.sketches.hive.theta.DataToSketchUDAF';

Run a query:

hive> select estimate(dataToSketch(myCol, 16384, 1.0)) from myTable where color = blue;
