I can see that we relocate akka's netty, akka uncommon math but also

be curious why Flink doesn't shaded all of akka dependencies...

Hello Haibo -

Yes, my application depends on Akka 2.5. 

Just curious, why do you think it's recommended to shade Akka version of my application instead of Flink ?

regards.

Hi  Debasish Ghosh,
 

Does your application have to depend on Akka 2.5? If not, it's a good idea to always keep the Akka version that the application depend on in line with Flink. 

If you want to try shading Akka dependency, I think that it is more recommended to shade Akka dependency of your application.

Best,

Haibo

Hello -

An application that uses Akka 2.5 and Flink 1.8.0 gives runtime errors because of version mismatch between Akka that we use and the one that Flink uses (which is Akka 2.4). Anyone tried shading Akka dependency with Flink ? 

Or is there any other alternative way to handle this issue ? I know Flink 1.9 has upgraded to Akka 2.5 but this is (I think) going to be a recurring problem down the line with mismatch between the new releases of Akka and Flink.

regards.
