[DISCUSS]Discussion on the problems that occur during the execution of flink tasks

Wechat group "Apache Linkis community Development group " chat records are as follows:


Speechless! :
@Mr.Lightning Did you use flink? I see that there is a package flink-connector-mysql-cdc that conflicts with the jetty-util package class name. Executing the flink task will report an error. How do you deal with this?


Mr. Lightning:
I use this cdc, and I seem to be looking for the same one, looking for an old version.


Speechless! :
Help me to see what version, I have a conflict according to the official website 1.1.1, my version is these two.



Mr. Lightning:
specific package name


Speechless! :



com.alibaba.ververica,flink-connector-mysql-cdc。



Speechless! :
ok I also change the version


Mr. Lightning:
What is the name of your conflicting package.


Speechless! :
org/eclipse/jetty/util/compression/DeflaterPool this.




Mr. Lightning:
My flink is 1.12.2


Speechless! :
mine too



Speechless! :
Strange, does your execution of flink tasks not report conflicts?


Mr. Lightning:
No, my version is different from yours


Speechless! :
I use linkis1.3.0, flink1.12.2


Mr. Lightning:
I said jetty version.


Speechless! :
I'll try it
