> Replace MD5 hash for lineage graph
> ----------------------------------
>
> Key: IMPALA-10207
> URL: https://issues.apache.org/jira/browse/IMPALA-10207
> Project: IMPALA
> Issue Type: Improvement
> Components: Frontend
> Affects Versions: Impala 4.0
> Reporter: Wenzhe Zhou
> Assignee: Wenzhe Zhou
> Priority: Major
> Labels: FIPS
> Fix For: Impala 4.0
>
>
> To support FIPS, we have to use FIPS-approved algorithms. In front end, we
> use MD5 hash algorithms to generate query hash for lineage graph. But MD5 is
> one of forbidden algorithms for FIPS. We have to replace MD5 with
> FIPS-approved algorithm, or non-cryptographic hash function like murmur3_128.
> We might need to figure out if there are external dependencies on the hash.
> e.g. the lineage graph was consumed by other component services, like Apache
> Atlas, and maybe they somehow rely on the hash being consistent across
> versions (seems unlikely).
