> Local properties set via sparkContext are not available as TaskContext
> properties when executing jobs and threadpools have idle threads which are
> reused
> Explanation:
> When SubqueryExec, the {{relationFuture}} is evaluated via a separate thread.
> The threads inherit the {{localProperties}} from sparkContext as they are the
> child threads.
> These threads are controlled via the executionContext (thread pools). Each
> Thread pool has a default {{keepAliveSeconds}} of 60 seconds for idle threads.
> Scenarios where the thread pool has threads which are idle and reused for a
> subsequent new query, the thread local properties will not be inherited from
> spark context (thread properties are inherited only on thread creation) hence
> end up having old or no properties set. This will cause taskset properties to
> be missing when properties are transferred by child thread via
> {{sparkContext.runJob/submitJob}}
