Anand Mazumdar updated MESOS-5359:
----------------------------------
Description:
Currently, the scheduler library {{src/scheduler/scheduler.cpp}} 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.
