> 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.
