Subject Re: Verifying that a query uses orc bloom filters, orc storage indexes

If you are using tez, you can verify that using counters that gets printed after query execution.
You need set hive.tez.exec.print.summary=true for tez to print counters after execution.

Is there any official way to verify that a query leveraged orc bloom filters or orc indexes?
For example, number of bytes (rows) not processed thanks to bloom filters or storage indexes?
Some indicators in the explain output?

Thank you.
