Apache Spark reassigned SPARK-20718:
------------------------------------
Assignee: (was: Apache Spark)
> FileSourceScanExec with different filter orders should be the same after
> canonicalization
> -----------------------------------------------------------------------------------------
>
> Key: SPARK-20718
> URL: https://issues.apache.org/jira/browse/SPARK-20718
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.2.0
> Reporter: Zhenhua Wang
>
> Since `constraints` in `QueryPlan` is a set, the order of filters can differ.
> Usually this is ok because of canonicalization. However, in
> `FileSourceScanExec`, its data filters and partition filters are sequences,
> and their orders are not canonicalized. So `def sameResult` returns different
> results for different orders of data/partition filters. This leads to, e.g.
> different decision for `ReuseExchange`, and thus results in unstable
> performance.
