Apache Flink

Hi, all. Can *`S3`* URL be used for specifying the jar location for application mode deployments? Last I tried Flink 1.18 + operator 1.9 they were still complaining that only *`local`* scheme was supported... Do I need to upgrade flink as well to 1.19.1? I'm pretty sure I saw S3 support for jarURI added in 1.19 version of Flink.

No, but apparently flink 1.19+ supports it. Gonna try soon.

Merely upgrading the operator to 1.9 is not enough.

yeah, I've been reading that you need to install the s3a plugin on the operator pod, and that should do it

it should just use the pluggable filesystems - but I can't find any docs on exactly *how*

jars with plugins go into plugins dir of the Flink distribution. The plugins had been around for a while. What wasn't supported before is having the jar on S3 - you had to create an init container on your application (Deployment mode) and place the jar with "local" protocol so blob server can serve it for task manager scaling operations.
