Mate Szalay-Beko commented on CURATOR-526:
------------------------------------------
So it looks to me that ZooKeeper is backward compatible and supports the old
config format (which seems to me still valid, if one doesn't use the dynamic
reconfig feature of the new ZooKeeper). However, Curator doesn't support the
old config format, and this leads to this error message.
> Error logged for valid config - "Invalid config event received: {properties}"

> Key: CURATOR-526
> URL: https://issues.apache.org/jira/browse/CURATOR-526
> Project: Apache Curator
> Issue Type: Bug
> Components: Framework
> Affects Versions: 4.0.1
> Reporter: Rajesh Singh
> Priority: Major
> Fix For: awaiting-response
>
>
> 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
