Compile datagen tool (derived from maropu/spark-tpcds-datagen).
cd tpcds/datagen
mvn package -DskipTests
Generate 1TB dataset with spark.
# use correct SPARK_HOME and output data location
# --use-double-for-decimal and --use-string-for-char are optional, see dsdgen usage
SPARK_HOME=$HOME/software/spark ./bin/dsdgen \
--output-location /user/hive/data/tpcds-1000 \
--scale-factor 1000 \
--format parquet \
--overwrite \
--use-double-for-decimal \
--use-string-for-char
Compile benchmark tool (derived from databricks/spark-sql-perf).
cd tpcds/benchmark-runner
mvn package -DskipTests
Edit your $SPARK_HOME/conf/spark-default.conf
to enable/disable Blaze (see the following conf), then launch benchmark runner.
If benchmarking with Blaze, ensure that the Blaze jar package is correctly built and moved into $SPARK_HOME/jars
. (How to build Blaze?)
# use correct SPARK_HOME and data location
SPARK_HOME=$HOME/software/spark ./bin/run \
--data-location /user/hive/data/tpcds-1000 \
--output-dir ./benchmark-result
Monitor benchmark status:
tail -f ./benchmark-result/YYYYMMDDHHmm/log
Summarize query times of all cases:
./bin/stat ./benchmark-result/YYYYMMDDHHmm
