> ScriptOperator spawns 2 threads for getting the stdout and stderr from the script and then forward the output from stdout to downstream operators. In case of any exceptions to the script (e.g., got killed), the ScriptOperator got an exception and throw it to upstream operators until MapOperator got it and call close(abort). Before the ScriptOperator.close() is called the script output stream can still forward output to downstream operators. We should terminate it immediately.
