Jungtaek Lim updated STORM-1224:
--------------------------------
Description:
In order to handle ack / fail easily, ShellBolt stores generated id and tuple
to Map, and remove it when subprocess passes ack or fail to that id.
In other word, if users doesn't let subprocess pass ack or fail, _input Map
only increases and never decreases. It would make memory issue when each tuple
is big or there're a lot of tuples flowing.
