Caizhi Weng created FLINK-20187:
-----------------------------------
Summary: FactoryUtil#createTableSource will be confused by a table
source and a table sink factory with same identifier
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
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);}}.
