cleanup ugly event messages in zookeeper client
-----------------------------------------------
Key: ZOOKEEPER-114
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-114
Project: Zookeeper
Issue Type: Improvement
Components: java client
Reporter: Patrick Hunt
Fix For: 3.0.0
Cleanup the event messages output by the java command line client:
The java client ZooKeeper.java has a process method in MyWatcher that prints
raw event information to the console. Many new users find this confusing (esp
since state changes have a null path).
public void process(WatcherEvent event) {
System.err.println(event.getPath() + ": " + event.getState() + "-"
+ event.getType());
}
If this is a state change we should print that, if it's an event we should
print that (state change doesn't have a path). Somewhere in the message we
should also indicate that the client received a watch notification from the
server.
