This repo contains sample user defined functions (UDFs) and user defined aggregate functions (UDAs) built against the Impala UDF/UDA framework.
To get started:
- Install the impala udf development package: http://archive.cloudera.com/cdh5/
- cmake .
- make
The samples will get built to build/. This contains test executables that you can run locally, without the impala service installed as well as the shared object artifacts that we can run on impala.
All contributions are to be code reviewed at gerrit.cloudera.org. We follow the same process and style as Apache Impala - see https://cwiki.apache.org/confluence/display/IMPALA/Impala+Home.
