If I want to check how the hive query converted into mapreduce code,
where can i check corresponding map reduce code for the hive query
MapReduce is used in back-end for every hive or Pig query we run, but we cannot check this MR codes. This is taken care by hadoop framework, and, rather than worrying about the back-end process, we should focus on hive/pig query. As writing a MR job is bit complex, so pig and hive came into existence (to make analysis simpler).
Hope this resolves your query
In case of any further issue,feel free to revert.
