Hive Tez reducers are running super slow

QUESTION

Hive Tez reducers are running super slow

Asked 2019-Sep-07 at 06:40

I have joined multiple tables and the total no of rows are around 25 billion. On top of that, I am doing aggregation. Here are my hive settings as below, which I am using to generate the final output. I am not really sure how to tune the query and make it run faster. Currently, I am doing trial and error and see if that can produce some results but that doesn't seem to be working.Mappers are running faster but reducers are taking forever to finish off. Could anyone share your thoughts on this? Thank you.
