Before this change, a single test database was created for the entire suite, and each test was marked to run serially. With the addition of a test fixture in tests/conftest.py to create a unique database per each individual method, it's possible now to run the tests in parallel. (The tables required by individual tests are created via local test fixtures.) As such, any methods which had been responsible for setting up the test database were removed. Pytest markers for running tests serially were also removed, except in cases where interactions from running concurrency would affect other tests. Additional minor changes were made to improve PEP-8 compliance. The non-serial tests were run in a loop ten times to confirm that there weren't any unexpected failures.

Welcome to Impala
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:
- Best of breed performance and scalability.
- Support for data stored in HDFS, Apache HBase and Amazon S3.
- Wide analytic SQL support, including window functions and subqueries.
- On-the-fly code generation using LLVM to generate CPU-efficient code tailored specifically to each individual query.
- Support for the most commonly-used Hadoop file formats, including the Apache Parquet (incubating) project.
- Apache-licensed, 100% open source.

Building Impala
This Apache Incubator repository is currently not buildable but has the complete source code for Impala minus some third-party dependences. See https://github.com/cloudera/Impala for the buildable Impala source and https://issues.cloudera.org/browse/IMPALA-3223 to track progress on making this repository buildable.
