Writing Storm Output To A File

Hi,

I am trying to write the results of my storm bolt into a simple text file
using the java PrintWriter. But the problem I am facing with it is that it
takes a long long time to write even a single storm emit record. This
decreases my storm processing speed with a great amount. So, any suggestion
on how to improve with this situation would be of great help.

Thanks and Regards,
Sitakanta Mishra

Put the record in the queue, start a thread to take the record to write files
