Hi guys, I am running Hive atop Tez and run several TPC-DS / TPC-H queries. I am trying to print the Key/Value pairs received as input by each vertex and generated as output accordingly.
However, looking at Hive / Tez code, it seems they are converted to Object type and use their serialized forms along. I would like to print the original content in <Key, Value> pairs both when generated and received by a vertex (just for the purpose of understanding). Could you please give me some hints on how I can do that? Thank you,Robert
