Jacques commented on IMPALA-10679:
----------------------------------

Thanks Zoltan. I can't comment on the impact of FIPS mode and it's 
requirements, but our use case for hash functions is not for secure encryption, 
but rather for generating keys in a warehousing scenario (specifically data 
vaults), so the security of the hash function is not such a big concern.

> Add support for the SHA2 family of hash functions (SHA-224, SHA-256, SHA-384, 
> and SHA-512).
> Hive already supports SHA2: HIVE-10644
> We should add a similar builtin function.
