Apache Spark reassigned SPARK-19213:
------------------------------------
Assignee: (was: Apache Spark)
> FileSourceScanExec usese sparksession from hadoopfsrelation creation time
> instead of the one active at time of execution
> ------------------------------------------------------------------------------------------------------------------------
>
> Key: SPARK-19213
> URL: https://issues.apache.org/jira/browse/SPARK-19213
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 2.1.0
> Reporter: Robert Kruszewski
>
> If you look at
> https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/execution/DataSourceScanExec.scala#L260
> you'll notice that the sparksession used for execution is the one that was
> captured from logicalplan. Whereas in other places you have
> https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/execution/DataSourceScanExec.scala#L154
> and SparkPlan captures active session upon execution in
> https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/execution/SparkPlan.scala#L52
> From my understanding of the io code it would be beneficial to be able to use
> the active session in order to be able to modify hadoop config without
> recreating the dataset. What would be interesting is to not lock the spark
> session in the physical plan for ios and let you share datasets across spark
> sessions. Is that supposed to work? Otherwise you'd have to get a new query
> execution to bind to new sparksession which would only let you share logical
> plans.
> I am sending pr along with the latter.
