I am using Hive and Impala on the same cluster. I find that when I create new tables, the Impala StateStore does not refresh automatically even after a few hours.

I know that I can accomplish this by running "refresh" in impala-shell (in a cron job if need be), but I would like to know: how often does impalad refresh metadata and can I set this interval to be shorter? If so, how?
