flink org.apache.flink.table.api.NoMatchingTableFactoryException - apache-flink

Question

I'm using flink table api, using kafka as input source and json as table schema. I got this error when submit my program:
```
The program finished with the following exception:
org.apache.flink.client.program.ProgramInvocationException: The main method caused an error.

Could anyone helps?

Try adding the kafka connector sql jar (e.g. flink-connector-kafka-0.11_2.11-1.6.1-sql-jar.jar). You can find the whole list of connector dependencies here.
