[jira] [Resolved] (MRUNIT-77) cannot use serializations that do not
clone into object, or serializations without no arg constructors with
reduce driver
[ https://issues.apache.org/jira/browse/MRUNIT-77?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
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

> @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)
