> I was playing with user-defined connectors when I found the following error
> message:
> ```
> 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:
> java.util.LinkedList
> java.util.LinkedList
> java.util.LinkedList
> java.util.LinkedList
> java.util.LinkedList
> java.util.LinkedList
> at
> org.apache.flink.table.factories.FactoryUtil.discoverFactory(FactoryUtil.java:258)
> at
> org.apache.flink.table.factories.FactoryUtil.getDynamicTableFactory(FactoryUtil.java:370)
> ... 71 more
> ```
> This is caused by {{FactoryUtil.java}} line 265, where {{.map(f ->
> factories.getClass().getName())}} should be {{.map(f ->
> f.getClass().getName())}}
