Local host has a critical service required by most of C/C++ functionality.
It is a HostInfoUtils.getHostInfo(ExecutionEnvironmentFactory.getLocal()).
Getting host info is a long operation that can throw exception.
To avoid catching exceptions a lot of C/C++ clients check availability of host info before getting one:

HostInfo hostInfo = null;
if (HostInfoUtils.isHostInfoAvailable(env)) {
  try {
    hostInfo = HostInfoUtils.getHostInfo(env);
  } catch (IOException | ConnectionManager.CancellationException ex) {
    Exceptions.printStackTrace(ex);
  }
}

This pattern resolves processing unexpected exceptions in C/C++ clients.
If all clients will be use such pattern the initializing of local host info is not occurred.

Local host info should initialized at startup IDE before using by C/C++ clients.
