Hi Team, I need some inputs from you. I have a requirement for my project where I have to join 21 hive external tables.
Out of which 6 tables are HUGE having 500 million records of data. Other 15 tables are smaller ones around 100 to 1000 records each. When I am doing inner joins/ left outer joins its taking hours to run the query. Please let me know some optimization techniques or any other eco system components that performs better than HIVE.
