Re: using thin jar to replace fat jar on yarn cluster mode
Hi zjfplayer, First, your user fat jar should not contains any flink dependents, them should be "provided". If your goal is to reduce the deployment time of task, and you are currently using session mode, you can consider putting jars directly under lib.

Hi, I think you can try specifying dependent jars with the -C option[1] when you submit the job, and see if that meets your needs.

Re: Re: using thin jar to replace fat jar on yarn cluster mode
When using yarn originally, we found a problem. The jars on yarn will take precedence over the jars on the specified classpath, and sometimes yarn is shared, and the jars in the lib directory of yarn cannot be modified. When Flink runs on a yarn cluster, is the jar on the classpath of flink itself higher than the jar on yarn? zjfpla...@hotmail.com From: tangjunli...@huitongjy.com<mailto:tangjunli...@huitongjy.com> Date: 2019-12-23 10:34 To: user-zh<mailto:user-zh@flink.apache.org> Subject: Re: using thin jar to replace fat jar on yarn cluster mode Specify classpath tangjunli...@huitongjy.com From: zjfpla...@hotmail.com Date: 2019-12-23 10:09 To: user; user-zh Subject: using thin jar to replace fat jar on yarn cluster mode Hi, Does flink on yarn support using thin jar to replace fat jar?

Hi, Does flink on yarn support using thin jar to replace fat jar? I don't want the jar of each flink task to have hundreds of MB. I want to put all the dependent packages in a single directory,and then the size of each flink task jar will be tens of KB. zjfpla...@hotmail.com
