Detailed Description

Utility class to help test UDAs. This can be used to test the correctness of the UDA, simulating multiple possible distributed execution setups. For example, the harness will run in the UDA in single node mode (so merge and serialize are unused), single level merge and multi-level merge. The test application is responsible for providing the data and expected result.

template<typename T >

static T impala_udf::UdaTestHarnessUtil::CopyIntermediate ( FunctionContext *  context, int  byte_size, const T &  src  )

inlinestatic

Copy src value into context, returning the new copy. This simulates copying the bytes between nodes.
