[jira] [Created] (AMBARI-16260) Hive View: Prevent multiple /database calls when the first call takes time or fails

DIPAYAN BHOWMICK created AMBARI-16260:
-----------------------------------------

             Summary: Hive View: Prevent multiple /database calls when the first call takes time or fails 
                 Key: AMBARI-16260
                 URL: https://issues.apache.org/jira/browse/AMBARI-16260
             Project: Ambari
          Issue Type: Bug
          Components: ambari-views
    Affects Versions: 2.2.0
            Reporter: DIPAYAN BHOWMICK
            Assignee: DIPAYAN BHOWMICK
             Fix For: 2.4.0


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.
