Summary: Replace MD5 hash with SHA-512 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
To support FIPS, we have to use FIPS-approved algorithms. We use MD5 hash
algorithms for lineage graph. But MD5 is one of forbidden algorithms. We have
to replace MD5 with FIPS-approved algorithms, like SHA-512.
We might need to figure out if there are external dependencies on the hash.
e.g. the lineage graph was consumed by component services, and maybe they
somehow rely on the hash being consistent across versions (seems unlikely).
