> This makes the UI almost unusable IMO (cc Carter Shanklin). The sample query 
> given on the page "select 1;" takes 10s for me. I know for a fact that hive 
> is faster than this.
> This is the limitation with the current implementation and Ambari framework. 
> We are limited to polling for results as opposed to the server push model and 
> hence there is the time lag between the submission of the query and the 
> result coming to the page. The polling interval is currently fixed to 10s and 
> we had a discussion internally in which we decided to reduce the polling 
> interval to 2-3 secs so that the queries as simple as this one is displayed 
> almost in no time.
