If you are using Tez, you can set hive.tez.exec.print.summary=true; in CLI to see the breakdown.

Subject: query execution

Hi,

I want to characterize the overhead for each step of a Hive query. The explain output doesn’t
give me the actual execution times, so how would I find those out?

Thanks in advance,

Shirley
