[jira] [Created] (MESOS-5359) The scheduler library should have a delay before initiating a connection with master.

             Summary: The scheduler library should have a delay before initiating a connection with master.
                 Key: MESOS-5359
                 URL: https://issues.apache.org/jira/browse/MESOS-5359
             Project: Mesos
          Issue Type: Bug
    Affects Versions: 0.29.0
            Reporter: Anand Mazumdar


Currently, the scheduler library does have an artificially induced delay when trying to initially establish a connection with the master. In the event of a master failover or ZK disconnect, a large number of frameworks can get disconnected and then thereby overwhelm the master with TCP SYN requests. 

On a large cluster with many agents, the master is already overwhelmed with handling connection requests from the agents. This compounds the issue further on the master.
