# This script can be executed in two ways:
# 1) Without any command line parameters - A normal data load will happen where data is
# generated as needed, generally by issuing 'INSERT INTO <table> SELECT *' commands.
# 2) With a command line parameter pointing to a test-warehouse snapshot file - In this
# case the snapshot file contents will be copied into HDFS prior to calling the data load
# scripts. This speeds up overall data loading time because it usually means only the
# table metadata needs to be created.
#
# For more information look at testdata/bin/load-test-warehouse-snapshot.sh and
# bin/load-data.py
