cloud-fan commented on issue #26473: [SPARK-29864][SPARK-29920][SQL] Strict parsing of day-time strings to intervals URL: https://github.com/apache/spark/pull/26473#issuecomment-558727199 I've figured out the problem: The Spark thrift server creates many SparkSessions to serve requests, and the thrift server serves requests using a single thread. One thread can only have one active SparkSession, so `SQLCong.get` can't get the proper conf from the session that runs the query. For this particular problem, a simple fix is ``` def sql(sqlText: String): DataFrame = { val tracker = new QueryPlanningTracker + SparkSession.setActiveSession(this) val plan = tracker.measurePhase(QueryPlanningTracker.PARSING) { sessionState.sqlParser.parsePlan(sqlText) } ``` But we should really think about how to set active session correctly.
