Hi.
Thanks Shammon. You are right org.apache.flink.streaming.connectors.kafka.table.KafkaDynamicTableFactory are not in the file.
I’m use the shade plugin as described and the only difference from my other project are the nested project structure. I have “my project”/Flink/“my flink project”/src/main/Java/…
So if you have any ideas why it isn’t shared correct it will help a lot Med venlig hilsen / Best regards Lasse Nedergaard

Hi, Lasse,
I think you should make sure the situation as Shammon said.
Maybe you need to use the maven-shade-plugin like this to package, and make sure files in `META-INF/services` are merged together.
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-shade-plugin</artifactId>
<version>3.2.4</version>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>shade</goal>
</goals>
<configuration>
<transformers>
<transformer implementation="org.apache.maven.plugins.shade.resource.ServicesResourceTransformer"/>
</transformers>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
Best, Hang Hi Lasse
I think you can first check whether there is a file `META-INF/services/org.apache.flink.table.factories.Factory` in your uber jar and there's `org.apache.flink.streaming.connectors.kafka.table.KafkaDynamicTableFactory` in the file. Flink would like to create table factory from that file. And then you can check whether your uber jar are in the classpath of flink cluster
Best, Shammon FY
Hi.
I have a simple job creating a table from Kafka. It works perfect on my local machine but when I build a Uber jar and use the official Flink image I get a validation exception.
Could not find any factory for identifier ‘Kafka’ that implements org.Apache.Flink.table.dynamicTableFactory in the class path.
The uber jar contains Flink-connector-kafka and Flink-sql-connector-Kafka.
I can see on my local machine it calls discovery factory in flink-table-common but on my cluster it use flink-table-api-java-Uber.
And the list of available identities doesn’t contain ‘Kafka’ and upsert-Kafka as It does on my local machine. 🤔
Anyone has a clue where I should look for the problem?
Med venlig hilsen / Best regards
