Giovanni Matteo Fumarola commented on YARN-8900:
------------------------------------------------

Thanks [~elgoiri] . 
 * Do you need to close the completion service?
No, there is no need to close them.
 * For the exception management, should we actually throw the exceptions instead of logging
and returning empty?
No, the second part of the Future execution will catch the exception.
