How about also printing the description below like;

if (args.length < 1) {
// scalastyle:off println
println(

at
|https://github.com/databricks/spark-sql-perf/blob/master/README.md to generate
the TPCDS data
|locally (preferably with a scale factor of 5 for benchmarking).
Thereafter, the value of
|dataLocation below needs to be set to the location where the
generated data is stored.
