> Key: FLINK-20187
> URL: https://issues.apache.org/jira/browse/FLINK-20187
> Project: Flink
> Issue Type: Bug
> Components: Table SQL / API
> Affects Versions: 1.12.0
> Reporter: Caizhi Weng
> Priority: Major
> Fix For: 1.12.0
>
>
> When creating a table source I'm faced with the following exception:
> ```
> Caused by: org.apache.flink.table.api.ValidationException: Multiple factories
> for identifier 'odps' that implement
> 'org.apache.flink.table.factories.DynamicTableFactory' found in the classpath.
> Ambiguous factory classes are:
> ```
> However there is only one table source factory with this identifier, and
> another table sink factory with this identifier.
> {{FactoryUtil#createTableSource}} shouldn't be confused.
> This is caused by {{FactoryUtil.java}} line 370, where {{factory =
> discoverFactory(context.getClassLoader(), DynamicTableFactory.class,
> connectorOption);}} should be {{factory =
> discoverFactory(context.getClassLoader(), factoryClass, connectorOption);}}.
