Tim Armstrong created IMPALA-7813:
-------------------------------------
Summary: Non-deterministic partition expression may be redundantly
evaluated
Key: IMPALA-7813
URL: https://issues.apache.org/jira/browse/IMPALA-7813
Project: IMPALA
Issue Type: Bug
Components: Frontend
Affects Versions: Impala 3.0, Impala 2.11.0
Reporter: Tim Armstrong
Following on from IMPALA-402, I believe there is another issue where the
partition value evaluated in the exchange, the sort and the table sink may all
turn out to be different values. This would break various clustering
optimisations and result in small files.
