A NullPointerException is possible when the StartupClusterConnectivityChecker fails, and one of the missing peers has been added/discovered after the initialization of the map between peers and datacenters. This is causing in some rare instances the NullPointerException because an "element cannot be mapped to a null key". This commit prevents the NullPointerException, by checking the map first for the DC and if it's null, it calls the `getDatacenterSource` function, which is a call to the `DatabaseDescriptor.getEndpointSnitch()::getDatacenter` method. -- This is an automated message from the Apache Git Service.
