Subject Re: using thin jar to replace fat jar on yarn cluster mode
Date Wed, 25 Dec 2019 04:01:46 GMT
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.
