Kudu allows specifying range partitions over multiple columns. Impala already has support for doing this when the partitions are specified with '=', but if the partitions are specified with '<' or '<=', the parser would return an error. This patch modifies the parser to allow for creating Kudu tables like: create table kudu_test (a int, b int, primary key(a, b)) partition by range(a, b) (partition (0, 0) <= values < (1, 1)); and similary to alter partitions like: alter table kudu_test add range partition (1, 1) <= values < (2, 2); Testing: - Modified functional_kudu.jointbl's schema so that we have a table in functional with a multi-column range partition to test things against. - Added FE and E2E tests for CREATE and ALTER.

This directory contains Impala test data sets. The directory layout is structured as follows: datasets/ <data set>/<data set>_schema_template.sql <data set>/<data files SF1>/data files <data set>/<data files SF2>/data files Where SF is the scale factor controlling data size. This allows for scaling the same schema to different sizes based on the target test environment.
