------------------------------------
Summary: Replace SqlConversionException with either TableException
or ValidationException
Key: FLINK-19395
URL: https://issues.apache.org/jira/browse/FLINK-19395
Project: Flink
Issue Type: Improvement
Components: Table SQL / Legacy Planner, Table SQL / Planner
Reporter: Timo Walther
We should avoid creating too many different exceptions without reason.
`SqlConversionException` is not necessary and can be replaced by the two
commonly used exceptions for TableException or ValidationException. Currently,
we throw all three in `SqlToOperation` converters.
