Subject Re:Re: Re: Re: Re: Re: Flink SQL job failed to submit with enableCheckpointing while SQL contains UDF
Date Mon, 02 Mar 2020 13:03:48 GMT




Hi, 
Yep, I am using 1.10
Did you submit the job in the cluster or just run it in your IDE? Because I can also run it
successfully in my IDE, but cannot run it through cluster by a shading jar. So I think maybe
the problem is related with maven jar classpath. But not sure about that. 


If you can submit the job by a shade jar through cluster , could you share the project pom
settings and sample test code ?
