>            Reporter: Vladimir Sitnikov

> CalciteException and SqlValidatorException log exceptions at ERROR level.
> This is not appropriate since
> 1) the exception might be expected by the caller
> 2) exception might contain sensitive information
> 3) ERROR level is not appropriate, since error in validation does not imply business-level error.
> I suggest to remove `LOGGER.error` calls from Calcite code.
> Logging exceptions at TRACE level is fine from my point of view, so client can enable trace logging if required for debug purposes.
