Description

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.
