Matt Burgess commented on NIFI-7904:
------------------------------------
The validation query isn't meant to do any real work, so I would think the Max
Wait Time property, or perhaps a DBCP property (which can be set on the
connection pool as a user-defined aka dynamic property) would suffice? Can you
explain the use case further?
> Support for validation query timeout in DBCP, Hive & HBase connection pools

> Different Implementation of ConnectionPools such as DBCP, Hive/Hive3 and
> Hadoop doesn't support query timeouts for validation queries. It is good to
> have timeouts when validation query takes longer time to execute instead of
> indefinite timeout.
