    Description

      When starting up a locator has no knowledge of cache servers that might be in the distributed system but it will process server-location requests from clients and return them incorrect information until it receives load info from the servers.

      In one test I saw a locator be ejected from the distributed system. When it auto-reconnected some cache clients asked it for server locations and, though there were 6 cache servers available the clients got this exception:

      ServerLocator has a readiness check but it is only testing to see if its DistributedSystem instance variable has been initialized. It ought to wait until it has received a server load update.
