Major Description
Curator Framework v4.0.1 - EnsembleTracker.processConfigData(byte[] data) (Ln: 157)- seems to be logging error for valid configs when the config string obtained from Zookeeper does not have the client info in it.
As per the docs the config string should conform to below formats:
server_config or server_config;client_config where server_config is host:port:port or host:port:port:type and client_config is port or host:port
In our case it conforms to the first pattern i.e. server_config with host:port:port:type
