cloud-fan commented on issue #27267: [SPARK-30556][SQL] Copy sparkContext.localproperties to child thread inSubqueryExec.executionContext URL: https://github.com/apache/spark/pull/27267#issuecomment-576595096 I think this is a common problem when we run code in a thread pool. I just realized that we hit a similar issue before with `SQLConf.get` and we add a hack to work around it. Shall we add a util function to easily capture the necessary thread locals and propagate them to thread pool? For example, we can add a `SQLExecution.withThreadLocalCaptured` ``` def withThreadLocalCaptured(f: => T): Future[T] = { val activeSession = ... val localProperties = ... // any other important thread locals? Future { // set active sessionn // set local properties f } } ```
