Kevin Zhang commented on FLINK-17745:
-------------------------------------

[~fly_in_gis] IIUC, the problem that [~Echo Lee] addresses is that both the fat 
jar and the jars extracted from the fat jar are added to `pipeline.jars`. 
Obviously this is retundant, and also I agree with lisen that only jars 
extraced from the fat jar should be added to `pipeline.jars`.

[~kkl0u]'s pr seems only set the fat jar to `pipeline.jars`, I'm not sure 
whether it works


> PackagedProgram' extractedTempLibraries and jarfiles may be duplicate

> When i submit a flink app with a fat jar, PackagedProgram will extracted temp 
> libraries by the fat jar, and add to pipeline.jars, and the pipeline.jars 
> contains  fat jar and temp libraries. I don't think we should add fat jar to 
> the pipeline.jars if extractedTempLibraries is not empty.
