Jakob Odersky commented on SPARK-7286:
--------------------------------------
Going through the code, I saw that catalyst also defines !== in its dsl, so it
seems this operator has quite wide-spread usage.
Would deprecating it in favor of something else be a viable option?
> Precedence of operator not behaving properly
> --------------------------------------------
>
> Key: SPARK-7286
> URL: https://issues.apache.org/jira/browse/SPARK-7286
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 1.3.1
> Environment: Linux
> Reporter: DevilJetha
> Priority: Critical
>
> The precedence of the operators ( especially with !== and && ) in Dataframe
> Columns seems to be messed up.
> Example Snippet
> .where( $"col1" === "val1" && ($"col2" !== "val2") ) works fine.
> whereas .where( $"col1" === "val1" && $"col2" !== "val2" )
> evaluates as ( $"col1" === "val1" && $"col2" ) !== "val2"
