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.
install impala udf.
