Hi, Can someone give me any advice on this? I have a hard time understanding how to properly get it. I observe that in ReduceSinkOperator.java, keys and values are available as HiveKey and BytesWritable, but I don't know how to extract the actual content. For key, I can use a StructObjectInspector and iterate over every getStructFieldsDataAsList(obj) element. Is this the right way to do it? However, for the value I have no clue how to get it.

However, I have a hard time to do that, as key / values are serialized. Is there any way I can see the original key / value details? Thanks in advance,Robert
