----------------------------------
Summary: Function resolution should be deterministic
Key: DRILL-2824
URL: https://issues.apache.org/jira/browse/DRILL-2824
Project: Apache Drill
Issue Type: Bug
Reporter: Mehant Baid
Assignee: Mehant Baid
Priority: Critical
Fix For: 1.0.0
Currently as part of function resolution we cost all the possible function
matches and pick the one with the best cost. However we simply pick the first
one with the best cost, there may be a possibility that we have multiple
functions that could have the same best cost and based on which function was
first in the map we will execute different functions on different clusters.
This JIRA aims to resolve functions in a deterministic way so we pick the same
function consistently.
