Calling `Await.result` will allow other tasks to be run on the same thread when using ForkJoinPool. However, SQL uses a `ThreadLocal` execution id to trace Spark jobs launched by a query, which doesn't work perfectly in ForkJoinPool. This PR just uses `Awaitable.result` instead to prevent ForkJoinPool from running other tasks in the current waiting thread. Jenkins Author: Shixiong Zhu <shixiong@databricks.com> Closes#15520 from zsxwing/SPARK-13747. (cherry picked from commit 7ac70e7) Signed-off-by: Shixiong Zhu <shixiong@databricks.com>
