* You can kickoff the 10 iterations of 1 TB run with

``curl https://raw.githubusercontent.com/hdinsight/HivePerformanceAutomation/master/tpch-scripts/RunTpch.sh | bash 1000 PASSWORD 10 ``

* You can run one iteration of the suite from the headnode of your cluster by running the following command from ``hive-testbench/tpch-scripts``

``./RunQueriesAndCollectPATData.sh SCALE_FACTOR CLUSTER_SSH_PASSWORD [RUN_ID]``

``RUN_ID`` is an optional argument. All the data for a run is collected under the ``hive-testbench/run_$RUN_ID`` folder. If the ``RUN_ID`` is not supplied then the current timestamp is used as the runId.

* You can run multiple iterations of the suite from the headnode of your cluster the following command from ``hive-testbench/tpch-scripts``

``./RunSuiteLoop REPEAT_COUNT SCALE_FACTOR CLUSTER_SSH_PASSWORD``

for ex: ``./RunSuiteLoop 10 1000 H@doop1234``
would run 10 iterations of the TPCH suite for a scale factor of 1000 (1TB)

* You can Run a Single Query from the headnode of your cluster by running the following command from ``hive-testbench/tpch-scripts``

``./TpchQueryExecute.sh SCALE_FACTOR QUERY_NUMBER [RUN_ID]``

* You can run multiple iterations of a single query by running the following command from ``hive-testbench/tpch-scripts``

``./RunSingleQueryLoop QUERY_NUMBER REPEAT_COUNT SCALCE_FACTOR CLUSTER_SSH_PASSWORD``

* you can run the following script from ``hive-testbench/tpch-scripts`` to get the perf data collected for a run

``./CollectPerfData.sh RUN_ID [RESULTS_DIR] [PERFDATA_OUTPUTDIR] [SERVER]``
``RUN_ID`` is the id of the run for which you want to collect perfdata
