hi
i want to set up a tpcds benchmark to test some performance of some spark
feature
i saw in TPCDSQueryBenchmark , it need send the --data-location to the
class, my question is how to generate the tpcds data in this benchmark
```
/**
* Benchmark to measure TPCDS query performance.
* To run this:
* {{{
* 1. without sbt:
* bin/spark-submit --jars <spark core test jar>,<spark catalyst test jar>
* --class <this class> <spark sql test jar> --data-location <location>
* 2. build/sbt "sql/test:runMain <this class> --data-location <TPCDS data
location>"
* 3. generate result: SPARK_GENERATE_BENCHMARK_FILES=1 build/sbt
* "sql/test:runMain <this class> --data-location <location>"
* Results will be written to "benchmarks/TPCDSQueryBenchmark-results.txt".
* }}}
*/
object TPCDSQueryBenchmark extends SqlBasedBenchmark with Logging {
```
