> 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.
