Review comment:
I debugged with your code, so the ZkClientPathMonitor objects are
currently only created in the register() method. So that's the reason we lose
the count if register later.
There is a simple fix, we can instantiate all the ZkClientPathMonitors in
the ZkClientMonitor constructor. Like this,
for (ZkClientPathMonitor.PredefinedPath path :
```
ZkClientPathMonitor.PredefinedPath.values()) {
// If monitor root path only, check if the current path is Root.
// Otherwise, add monitors for every path.
if (!_monitorRootOnly ||
path.equals(ZkClientPathMonitor.PredefinedPath.Root)) {
_zkClientPathMonitorMap.put(path,
new ZkClientPathMonitor(path, _monitorType, _monitorKey,
_monitorInstanceName));
}
}
```
Then in the register(), just register all the ZkClientPathMonitor objects
that are in the _zkClientPathMonitorMap.
The good thing is that it seems to be the right thing to do.
