             Summary: Fix an error in BenchmarkBase.scala that occurs when creating a benchmark file in a non-existent directory
                 Key: SPARK-35266
                 URL: https://issues.apache.org/jira/browse/SPARK-35266
             Project: Spark
          Issue Type: Bug
          Components: Tests
    Affects Versions: 3.2.0
            Reporter: Byungsoo Oh


When submitting a benchmark job using _org.apache.spark.benchmark.Benchmarks_ class with _SPARK_GENERATE_BENCHMARK_FILES=1_ option, an exception is raised if the directory where the benchmark file will be generated does not exist.
 For example, if you execute _BLASBenchmark_ like the command below, you get an error unless you manually create _benchmarks/_ directory under _spark/mllib-local/_.
{code:java}
SPARK_GENERATE_BENCHMARK_FILES=1 bin/spark-submit \
--driver-memory 6g --class org.apache.spark.benchmark.Benchmarks \
--jars "`find . -name '*-SNAPSHOT-tests.jar' -o -name '*avro*-SNAPSHOT.jar' | paste -sd ',' -`" \
"`find . -name 'spark-core*-SNAPSHOT-tests.jar'`" \
"org.apache.spark.ml.linalg.BLASBenchmark"
{code}
This is caused by the code in _BenchmarkBase.scala_ where an attempt is made to create the benchmark file without validating the path.
