> If I am not able to instantiate MetaListener or HookContext because of some
> dependent class missing, the only error I get is InvocationTargetException.
> MetaStoreUtils.getMetaListener should be changed as following:
> try {
> T listener = (T) Class.forName(
> listenerImpl.trim(), true,
> JavaUtils.getClassLoader()).getConstructor(
> Configuration.class).newInstance(conf);
> listeners.add(listener);
> } catch (InvocationTargetException e) {
> throw new MetaException("Failed to instantiate listener named: "+
> listenerImpl + " reason: " + e.getCause().toString());
> } catch (Exception e) {
> throw new MetaException("Failed to instantiate listener named: "+
> listenerImpl + " reason: " + e.toString());
> }
> Similarly Driver.getHooks should be changed to handle
> InvocationTargetException in a better way.
