Hadoop Connect - how to change the polling frequency of HDFS file lists, to a longer duration.?

I'm using HadoopConnect. But, its creating pressure on name node with too many frequent requests for listing of files with -lsr recursive. How do we change the frequency to say every 5 or 10 minutes than every minute. I'm looking for something similar to "auto" in Hadoop DB connect / settings. where we can configure the poll frequency.

Thanks.
