Dimitris Tsirogiannis c2abcd6f3d Query transformation of nested queries.

This commit implements nested queries with [NOT] IN, [NOT] EXISTS and
aggregate subquery predicates in Impala. The following cases are
supported:
1. Correlated and uncorrelated [NOT] IN.
2. Correlated [NOT] EXISTS.
3. Correlated and uncorrelated aggregate subqueries.

README

This directory contains Impala test workloads. The directory layout for the workloads should follow:

workloads/
   <data set name>/<data set name>_dimensions.csv  <- The test dimension file
   <data set name>/<data set name>_core.csv  <- A test vector file
   <data set name>/<data set name>_pairwise.csv
   <data set name>/<data set name>_exhaustive.csv
   <data set name>/queries/<query test>.test <- The queries for this workload
