---------------------------------------
Summary: locator returns incorrect server information when
starting up
Key: GEODE-1393
URL: https://issues.apache.org/jira/browse/GEODE-1393
Project: Geode
Issue Type: Bug
Components: locator
Reporter: Bruce Schuchardt
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.
