Eric Liang created SPARK-23809:
----------------------------------
Summary: Active SparkSession should be set by getOrCreate
Key: SPARK-23809
URL: https://issues.apache.org/jira/browse/SPARK-23809
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 2.4.0
Reporter: Eric Liang
Currently, the active spark session is set inconsistently (e.g., in
createDataFrame, prior to query execution). Many places in spark also
incorrectly query active session when they should be calling
activeSession.getOrElse(defaultSession).
The semantics here can be cleaned up if we also set the active session when the
default session is set.
