All versions of GemFire
Pool properties read-timeout and retry-attempts are not applicable to locator connections.
The GemFire client-pool connection properties 'read-timeout' and 'retry-attempts' are only applicable when a client is connected to a server and are not applicable to locator connections. Hence, if locator is not available, a client will throw a LocatorNotAvailable exception and there is no way to retry on locator.
Additionally, when a locator is removed from the locator list due to unexpected exception retry attemps will not work.
