Hi Leonard, Chesnay, thanks for having a look. I was able to sort this out -it was because of the change in default Class Loading policy becoming child-first introduced in 1.10 through https://issues.apache.org/jira/browse/FLINK-13749 . Once I changed it back to parent-first, I was able to submit jobs.
Hopefully any other devs who have similar issues will find this thread useful :) // ah From: Leonard Xu <xbjt...@gmail.com> Sent: Friday, October 16, 2020 1:10 AM To: Chesnay Schepler <ches...@apache.org> Cc: Hailu, Andreas [Engineering] <andreas.ha...@ny.email.gs.com>; user@flink.apache.org Subject: Re: Runtime Dependency Issues Upgrading to Flink 1.11.2 from 1.9.2 Hi, Chesnay @Leonared I noticed you handled a similar case on the Chinese ML in July<https://urldefense.proofpoint.com/v2/url?u=http-3A__apache-2Dflink.147419.n8.nabble.com_flink1-2D11-2Dtd5154.html&d=DwMFoQ&c=7563p3e2zaQw0AB1wrFVgyagb2IE5rTZOYPxLxfZlX4&r=hRr4SA7BtUvKoMBP6VDhfisy2OJ1ZAzai-pcCC6TFXM&m=x3wVpzZtiuEaKQGifHliLwtb0J_8oiqzJoNrUxV19sE&s=ymvt_cFkIWmVUru2K5T3DxHuwJ3CSHc_3s9hdk3W4T4&e=>, do you have any insights?

The only changes were the update the 1.11.2 runtime dependencies listed earlier, as well as compiling with the flink-clients in some of our modules since we were relying on the transitive dependency. Our 1.9.2 jobs are still able to run just fine, which is interesting. // ah From: Chesnay Schepler <ches...@apache.org><mailto:ches...@apache.org> Sent: Thursday, October 15, 2020 7:34 AM To: Hailu, Andreas [Engineering] <andreas.ha...@ny.email.gs.com><mailto:andreas.ha...@ny.email.gs.com>; user@flink.apache.org<mailto:user@flink.apache.org> Subject: Re: Runtime Dependency Issues Upgrading to Flink 1.11.2 from 1.9.2 I'm not aware of any Flink module bundling this class. Note that this class is also bundled in jersey-core (which is also on your classpath), so it appears that there is a conflict between this jar and your shaded one.
