问题
I have recently migrated storm version from 0.8.2 to 0.9.4. In 0.8.2 I had implemented tick tuple functionality in a bolt in my code.
When I used to run the topology it used to trigger periodic activity after the time specified in tickfrequency seconds (configured in getComponentConfiguration method).
But the same piece of code is not running in apache storm version 0.9.4. The code inside if block in execute method is never getting executed because isTickTuple method is always returning false.
The other functionalities are working perfectly in apache storm 0.9.4 but tick tuple is not functioning as expected. Can you help?
