Hi David,
this seems to be a bug in our s3 plugin. The joda dependency should be
bundled there.
Are you using s3 as a plugin by any chance? Which flink version are you
using?
If you are using s3 as a plugin, you could put joda in your plugin folder
like this
flink-dist
├── conf
├── lib
...
└── plugins
└── s3
├── joda.jar
└── flink-s3-fs-hadoop.jar
If flink-s3-fs-hadoop.jar is in lib, you could try adding joda into that.
Adding joda to your user code will unfortunately not work.
Best,
Arvid
