From the readme:
3. imp: This is the the set of queries created by Cloudera for testing in Impala.
The queries are available to provide an apples to apples comparison of run times to
compare with Impala. The queries were copied from this public repo:
https://github.com/cloudera/impala-tpcds-kit
The license file for these queries is also included:
impala_queries_license.txt
The Impala queries were changed for syntax and to remove partition cheating. Impala
doesn't support the concatenation with || so they changed the SQL to use their concat()
function. This was changed back. Intervals were changed from "interval 30 days" to
"'30 days'::interval". Query hints were removed. There are 117 removals of explicit
partition pruning in 63 unique queries. Queries 3, 4, 7, 9, 14, 24, 35, 46, and 51 were
heavily modified by Cloudera so reverting to the original TPC-DS version.
