## What changes were proposed in this pull request? regexp_extract actually returns null when it shouldn't when a regex matches but the requested optional group did not. This makes it return an empty string, as apparently designed. ## How was this patch tested? Additional unit test Author: Sean Owen <sowen@cloudera.com> Closes #14504 from srowen/SPARK-16409. |

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
