Summary: Make "histogram" and "sample" ineligible for tuple caching
Key: IMPALA-13901
URL: https://issues.apache.org/jira/browse/IMPALA-13901
Project: IMPALA
Issue Type: Task
Components: Frontend
Affects Versions: Impala 5.0.0
Reporter: Joe McDonnell
"histogram" and "sample" use the same infrastructure as "appx_median", which
includes randomness. These functions should be marked ineligible for tuple
caching. This came up in some test cases when running with tuple cache
verification.
