The “trick” behind the following Python code is that we will use the Hadoop Streaming API (see also the corresponding wiki entry) for helping us passing data between our Map and Reduce code via STDIN (standard input) and STDOUT (standard output). We will simply use Python’s sys.stdin to read input data and print our own output to sys.stdout. That’s all we need to do because Hadoop Streaming will take care of everything else! Good understanding of Hadoop concepts including file system and Map Reduce. Hands on experience on Spark framework, Unix scripting, Hive queries, wriring UDF in Hive. Theoritical knowledge and POC alone will not suffice.

MapReduce API (org.apache.hadoop.mapreduce). Similarily to the mapreduce package, it's possible with the mapred API to implement your own Mapper s and Reducer s directly using the public classes provided in these libraries. Generate the python code with Thrift 0.9. Hue does it with this script regenerate_thrift.sh. Implement it. This is hive_server2_lib.py. An extra layer (dbms.py) has been added in order to simplify the use of the raw API and keep compatibility with Beeswax (ancestor of Hive Server 2). This is what we use in the above example.
