Jim Donofrio resolved MRUNIT-77.
--------------------------------
Resolution: Fixed
added above test
set value to copy(next, value, conf) for serializations that do not change the
copy argument
remove initialization of value by ReflectionUtil for classes without no arg
constructors
committed in 1299156
> cannot use serializations that do not clone into object, or serializations
> without no arg constructors with reduce driver

> Issue Type: Bug
> Affects Versions: 0.8.1
> Reporter: Jim Donofrio
> Assignee: Jim Donofrio
> Fix For: 1.0.0

>
> @Test
> public void testJavaSerialization() {
> ReduceDriver<Integer, Integer, Integer, Integer> driver =
> ReduceDriver.newReduceDriver(new IdentityReducer<Integer, Integer>());
> Configuration conf = new Configuration();
> conf.set("io.serializations",
> "org.apache.hadoop.io.serializer.JavaSerialization");
> driver.setConfiguration(conf);
> driver.withInputKey(1)
> .withInputValue(2)
> .withInputValue(3)
> .withInputValue(4)
> .withOutput(1, 2)
> .withOutput(1, 3)
> .withOutput(1, 4)
> .runTest();
> }
> The above test fails because the result of copy(next, value, conf) needs to
> be reassigned to value for serializations such as java serialization that
> dont change the copy argument. This also fails because of the lack of a no
> arg constructor which breaks the call to ReflectionUtils.newInstance(klass,
> conf)
