> When a hive view is opened /database calls gets called every 15 secs. There
> could be a situation that if getting a connection from HS2 takes time, these
> calls would pile up and would exhaust jetty threads quickly rendering ambari
> unusable in some time.
> Hence, it will be good to prevent these subsequent /database calls till the
> current call gives a response or errors out.
