> -----------------------------------------------
>
> Key: HIVE-12044
> URL: https://issues.apache.org/jira/browse/HIVE-12044
> Project: Hive
> Issue Type: Bug
> Components: CBO
> Affects Versions: 2.0.0
> Reporter: Jesus Camacho Rodriguez
> Labels: newbie++
>
> The logic of traversing expressions (ExtractCommonOperands) is not recursive
> and misses many of the use cases.
> Also check for comparison need to take in to account functions (ex: ((x+y)=10
> and z=1) or ((x+y)=10 and z=2) ).
