How to keep running topology if no input stream ?

Hi, I am running storm in local mode, I am running twitter hashtag count
example, but when there is no tweets to process topology stops running ? So
how to keep topology in sleep mode if there is no data to process and when
data is available it will start processing.

Topology not stops when there is no data. It still runs and waits for 
more data.
