Github user liancheng commented on a diff in the pull request:

    This line is actually moved to `optimizedPlan`. It's for fixing the streaming test failures.
    Although streaming queries doesn't use `QueryExecution` for actual execution, it somehow
triggers this line after changes made in the previous commit and throws exception. Not quite
familiar with structured streaming though, I may missed something here.
