Actually I have worked on IntelliJ only. As you said I also suspect the fat jar (created from intelliJ) is unable to have the link to the native library when I generate it and also the maven plugin is present in the pom.xml . I also used another fat jar creator application to create the fat jar and link it manually with my native library. In the second case I do not find the error of linking however I get a new error:
org.apache.flink.client.program.ProgramInvocationException: The program plan could not be fetched - the program aborted pre-maturely. However the program is executing all the steps it is required to do because I can see all the files written properly as expected.

I am not sure but the reason could be that you are not submitting "fat-jar" containing all the libs when submitting it to job manager. 

When you run it through intellij it takes care of including the libraries.

To create fat jar use maven-shade-plugin.

Let me know if it works.

Thanks,

I was trying to run a basic program in java by submitting to the job manager in Flink. I have a native library from open CV. When I try to submit the job I get "java.lang.UnsatisfiedLinkError: no opencv_java310 in java.library.path", however when I run it on Intellij by setting up the flink execution environment I get correct results. I have followed some solutions from the apache flink support website:https://mail-archives.apache.org/mod_mbox/flink-user/201604.mbox/%3CCAO0MGUj_h==sw76-TWF6x8fnT_Vdc84mwu=YLejjn=bG-up+MQ@...%3E and have modified my conf.yaml file accordingly (by pointing env.java.opts: -Djava.library.path="/path of Open CV library", but no luck, Maybe my question is very basic , but still I am stuck, any help would be highly appreciated.

 Thanks :-)
