You might want to consider populating the right hand side of this expression
local_dt >= date_sub(to_date(unix_timestamp()), 3)
in the Hive client code that is issuing the Hive query.

Subject: Get current date in hive
How do I get the current date in Hive? Specifically, I’m looking for the equivalent of following SQL where clause:
where LOCAL_DT >= current date - 3 day
I tried using
where local_dt >= date_sub(to_date(unix_timestamp()), 3)
but this method seems to be many times slower than hardcoding the date. local_dt is the local date and also the partition key for the table.
