> Currently {{HMSHandler}} will convert {{NoSuchObjectException}} and
> {{InvalidOperationException}} to {{MetaException}}, but it will lose the root
> cause. The related code as follows:
> {code:java}
> // HMSHandler.java#L3956
> private void firePreEvent(PreEventContext event) throws MetaException {
> for (MetaStorePreEventListener listener : preListeners) {
> try {
> listener.onEvent(event);
> } catch (NoSuchObjectException e) {
> throw new MetaException(e.getMessage());
> } catch (InvalidOperationException e) {
> throw new MetaException(e.getMessage());
> }
> }
> }
> {code}
> In this patch, we want to add the root cause and it can help troubleshooting
> through HMS log.
