Review comment:
Actually you don't need this `timedWait` method. You can still use same
`await(timeout)` as you were using earlier. But outside while loop you can do
below check to get the exception in error condition. Check
[here](https://github.com/apache/drill/blob/master/exec/java-exec/src/main/java/org/apache/drill/exec/work/prepare/PreparedStatementProvider.java#L158)
```
// check if query completed with exception
if (isComplete && webUserConnection.getError() != null) {
throw new UserRemoteException(webUserConnection.getError());
}
```
