tpcds-hdinsight

Goal of this project is to help generate TPCDS data with hive and create your own HDInsight benchmarks for various engines

  1. Hive
  2. Interactive Hive(LLAP)
  3. Spark
  4. Presto

How to use with Hive CLI

  1. Clone this repo.

    git clone https://github.com/hdinsight/tpcds-hdinsight/ && cd tpcds-hdinsight
  2. Run TPCDSDataGen.hql with settings.hql file and set the required config variables.

    /usr/bin/hive -i settings.hql -f TPCDSDataGen.hql -hiveconf SCALE=10 -hiveconf PARTS=10 -hiveconf LOCATION=/HiveTPCDS/ -hiveconf TPCHBIN=resources 

    Here,

    SCALE is a scale factor for TPCDS. Scale factor 10 roughly generates 10 GB data, Scale factor 1000 generates 1 TB of data and so on.

    PARTS is a number of task to use for datagen (parrellelization). This should be set to the same value as SCALE.

    LOCATION is the directory where the data will be stored on HDFS.

    TPCHBIN is where the resources are found. You can specify specific settings in settings.hql file.

  3. Now you can create tables on the generated data.

    /usr/bin/hive -i settings.hql -f ddl/createAllExternalTables.hql -hiveconf LOCATION=/HiveTPCDS/ -hiveconf DBNAME=tpcds

    Generate ORC tables and analyze

    hive -i settings.hql -f ddl/createAllORCTables.hql -hiveconf ORCDBNAME=tpcds_orc -hiveconf SOURCE=tpcds
    hive -i settings.hql -f ddl/analyze.hql -hiveconf ORCDBNAME=tpcds_orc 
  4. Run the queries !

    /usr/bin/hive -database tpcds_orc -i settings.hql -f queries/query12.sql 

How to use with Beeline CLI

  1. Clone this repo.

    git clone https://github.com/hdinsight/tpcds-hdinsight && cd tpcds-hdinsight
  2. Upload the resources to DFS.

    hdfs dfs -copyFromLocal resources /tmp
  3. Run TPCDSDataGen.hql with settings.hql file and set the required config variables.

    beeline -u "jdbc:hive2://`hostname -f`:10001/;transportMode=http" -n "" -p "" -i settings.hql -f TPCDSDataGen.hql -hiveconf SCALE=10 -hiveconf PARTS=10 -hiveconf LOCATION=/HiveTPCDS/ -hiveconf TPCHBIN=`grep -A 1 "fs.defaultFS" /etc/hadoop/conf/core-site.xml | grep -o "wasb[^<]*"`/tmp/resources  
    Here, 
    

    SCALE is a scale factor for TPCDS. Scale factor 10 roughly generates 10 GB data, Scale factor 1000 generates 1 TB of data and so on.

    PARTS is a number of task to use for datagen (parrellelization). This should be set to the same value as SCALE.

    LOCATION is the directory where the data will be stored on HDFS.

    TPCHBIN is where the resources are found. You can specify specific settings in settings.hql file.

  4. Now you can create tables on the generated data.

    beeline -u "jdbc:hive2://`hostname -f`:10001/;transportMode=http" -n "" -p "" -i settings.hql -f ddl/createAllExternalTables.hql -hiveconf LOCATION=/HiveTPCDS/ -hiveconf DBNAME=tpcds

    Generate ORC tables and analyze

    beeline -u "jdbc:hive2://`hostname -f`:10001/;transportMode=http" -n "" -p "" -i settings.hql -f ddl/createAllORCTables.hql -hiveconf ORCDBNAME=tpcds_orc -hiveconf SOURCE=tpcds
    beeline -u "jdbc:hive2://`hostname -f`:10001/;transportMode=http" -n "" -p "" -i settings.hql -f ddl/analyze.hql -hiveconf ORCDBNAME=tpcds_orc 
  5. Run the queries !

    beeline -u "jdbc:hive2://`hostname -f`:10001/tpcds_orc;transportMode=http" -n "" -p "" -i settings.hql -f queries/query12.sql 

If you want to run all the queries 10 times and measure the times it takes, you can use the following command:

for f in queries/*.sql; do for i in {1..10} ; do STARTTIME="`date +%s`";  beeline -u "jdbc:hive2://`hostname -f`:10001/tpcds_orc;transportMode=http" -i settings.hql -f $f  > $f.run_$i.out 2>&1 ; SUCCESS=$? ; ENDTIME="`date +%s`"; echo "$f,$i,$SUCCESS,$STARTTIME,$ENDTIME,$(($ENDTIME-$STARTTIME))" >> times_orc.csv; done; done;

FAQ

Does it work with scale factor 1?

No. The parrellel data generation assumes that scale > 1. If you are just starting out, I would suggest you start with 10 and then move to standard higher scale factors (100, 1000, 10000,..)

Do I have to specify PARTS=SCALE ?

Yes.

How do I avoid my session getting killed due to network errors while long running benchmark?

Use byobu. Type byobu which will start a new session and then run the command. It will be there when you come back even if your network connection is broken.

How do I generate partitioned text tables ?

After generating raw data(step 3a), use the following command:

hive -i settings.hql -f ddl/createAllTextTables.hql -hiveconf TEXTDBNAME=tpcds_text -hiveconf SOURCE=tpcds

This will generate tpcds_text database with all the tables in text format.

How do I generate Parquet data?

After generating raw data(step 3a), use the following command:

hive -i settings.hql -f ddl/createAllParquetTables.hql -hiveconf PARQUETDBNAME=tpcds_pqt -hiveconf SOURCE=tpcds

This will generate tpcds_pqt database with all the tables in parquet format.

How do I run the queries with Spark?

Spark thriftserver listens on 10002 instead of hive thrift server listening on 10001. So replace the connection url appropriately. For example, running the all the queries 10 times with Spark,

for f in queries/*.sql; do for i in {1..10} ; do STARTTIME="`date +%s`";  beeline -u "jdbc:hive2://`hostname -f`:10002/tpcds_orc;transportMode=http" -i sparksettings.hql -f $f  > $f.run_$i.out 2>&1 ; SUCCESS=$? ; ENDTIME="`date +%s`"; echo "$f,$i,$SUCCESS,$STARTTIME,$ENDTIME,$(($ENDTIME-$STARTTIME))" >> times_orc.csv; done; done;

How do I run the queries with Presto?

presto --schema tpcds_orc -f queries/query12.sql

You can run all the queries 10 times with presto with the following command,

for f in queries/*.sql; do for i in {1..10} ; do STARTTIME="`date +%s`"; presto --schema tpcds_orc -f $f  > $f.run_$i.out 2>&1 ; SUCCESS=$? ; ENDTIME="`date +%s`"; echo "$f,$i,$SUCCESS,$STARTTIME,$ENDTIME,$(($ENDTIME-$STARTTIME))" >> times_orc.csv; done; done;
You can’t perform that action at this time.
