Description
Currently there are two classes with the same naming BenchmarkBase:
1. org.apache.spark.util.BenchmarkBase
2. org.apache.spark.sql.execution.benchmark.BenchmarkBase
Here I propose:
1. the package org.apache.spark.util.BenchmarkBase should be in test package, move to org.apache.spark.sql.execution.benchmark .
2. Rename the org.apache.spark.sql.execution.benchmark.BenchmarkBase as BenchmarkWithCodegen
3. Move org.apache.spark.util.Benchmark to test package of org.apache.spark.sql.execution.benchmark
