Andrew Ray d8f528ceb6 [SPARK-13749][SQL][FOLLOW-UP] Faster pivot implementation for many distinct values with two phase aggregation ## What changes were proposed in this pull request? This is a follow up PR for #11583. It makes 3 lazy vals into just vals and adds unit test coverage. ## How was this patch tested? Existing unit tests and additional unit tests. Author: Andrew Ray <ray.andrew@gmail.com> Closes #12861 from aray/fast-pivot-follow-up.		2016-05-02 22:47:32 -07:00

Notes for Parquet compatibility tests

The following directories and files are used for Parquet compatibility tests:

.
├── README.md                   # This file
├── avro
│   ├── *.avdl                  # Testing Avro IDL(s)
│   └── *.avpr                  # !! NO TOUCH !! Protocol files generated from Avro IDL(s)
├── gen-java                    # !! NO TOUCH !! Generated Java code
├── scripts
│   ├── gen-avro.sh             # Script used to generate Java code for Avro
│   └── gen-thrift.sh           # Script used to generate Java code for Thrift
└── thrift
    └── *.thrift                # Testing Thrift schema(s)

To avoid code generation during build time, Java code generated from testing Thrift schema and Avro IDL are also checked in.

When updating the testing Thrift schema and Avro IDL, please run gen-avro.sh and gen-thrift.sh accordingly to update generated Java code.

Prerequisites

Please ensure avro-tools and thrift are installed. You may install these two on Mac OS X via:

$ brew install thrift avro-tools
