> The ListHDFS processor successfully retains state in zookeeper; however, state is not
properly cleared.  You can right click, select "view state" , and then "clear state"; however,
regardless of what the state window shows state is still retained in zookeeper.  If a new
file that was not previously seen before is listed by the ListHDFS processor, all previous
state is repopulated in the view state window. Files will not be picked up again unless the
ListHDFS processor is replaced by a new one.
