## Package org.apache.hadoop.registry.client.exceptions Description

Registry Service Exceptions

These are the Registry-specific exceptions that may be raised during Registry operations.

Other exceptions may be raised, especially `IOExceptions` triggered by network problems, and `IllegalArgumentException` exceptions that may be raised if invalid (often null) arguments are passed to a method call.

All exceptions in this package are derived from `RegistryIOException`
