------------------------------------------

             Summary: Silence ERROR logs from CalciteException, SqlValidatorException
                 Key: CALCITE-2463
                 URL: https://issues.apache.org/jira/browse/CALCITE-2463
             Project: Calcite
          Issue Type: Bug
          Components: core
    Affects Versions: 1.17.0
            Reporter: Vladimir Sitnikov
            Assignee: Julian Hyde


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.
