    Description

      QuantileSummaries is a useful utility class to do statistics. It can be used by aggregation function like percentile_approx.

      Currently, QuantileSummaries is located at project catalyst in package org.apache.spark.sql.execution.stat, probably, we should move it to project catalyst package org.apache.spark.sql.util.
