Robert Kruszewski created SPARK-19213:
-----------------------------------------

             Summary: 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.
