Jim Donofrio commented on MRUNIT-13:
------------------------------------
To do this I guess we need to have a MockRecordWriter returned from a
MockOutputFormat. Users will specify everything that they usually specify for
MultipleOutputs except for the OutputFormat. The MockRecordWriter will store
all the results in a list as we do now with the MockOutputCollector. Then the
problem is how we pass this list back to the MapDriver or ReduceDriver. The
only shared object we would have access to is the JobConf. We can then use the
Serialization classes to serialize the objects out to bytes, convert the bytes
into a string using their hex representation to prevent the String decode from
messing anything up. Then we can store the hex strings in the conf and
deserialize them out in the MapDriver or ReduceDriver to verify the actual
output matches the requested output for each multipleoutputs type.
I recognize this isnt the cleanest solution but this will be easier for the
user and I am not sure this is another way of doing this. Any thoughts?
