IMPALA-9529: Fix multi-tuple predicates not assigned in column masking Column masking is implemented by replacing the masked table with a table masking view which has masked expressions in its SelectList. However, nested columns can't be exposed in the SelectList, so we expose them in the output field of the view in IMPALA-9330. As a result, predicates that reference both primitive and nested columns of the masked table become multi-tuple predicates (referencing tuples of the view and the masked table). Such kinds of predicates are not assigned since they no longer bound to the view's tuple or the masked table's tuple. We need to pick up the masked table's tuple id when getting unassigned predicates for the table masking view. Also need to do this for assigning predicates to the JoinNode which is the only place that introduces multi-tuple predicates. Tests: - Add tests with multi-tuple predicates referencing nested columns. - Run CORE tests.

Lightning-fast, distributed SQL queries for petabytes of data stored in Apache Hadoop clusters.
Impala is a modern, massively-distributed, massively-parallel, C++ query engine that lets you analyze, transform and combine data from a variety of data sources:
To learn more about Impala as a business user, or to try Impala live or in a VM, please visit the Impala homepage.
If you are interested in contributing to Impala as a developer, or learning more about Impala's internals and architecture, visit the Impala wiki.
Impala only supports Linux at the moment.
This distribution uses cryptographic software and may be subject to export controls. Please refer to EXPORT_CONTROL.md for more information.
See bin/bootstrap_build.sh.
Impala can be built with pre-built components or components downloaded from S3. The components needed to build Impala are Apache Hadoop, Hive, HBase, and Sentry. If you need to manually override the locations or versions of these components, you can do so through the environment variables and scripts listed below.
Location | Purpose |
---|---|
bin/impala-config.sh | This script must be sourced to setup all environment variables properly to allow other scripts to work |
bin/impala-config-local.sh | A script can be created in this location to set local overrides for any environment variables |
bin/impala-config-branch.sh | A version of the above that can be checked into a branch for convenience. |
bin/bootstrap_build.sh | A helper script to bootstrap some of the build requirements. |
bin/bootstrap_development.sh | A helper script to bootstrap a developer environment. Please read it before using. |
