Hi,Yun Tang
Thanks for help. The first option makes the package process heavy, the second
will make a change to flink’s lib folder. And the -yt cannot help also, because
I need these dependencies before it’s submitted on yarn, and I did use -yt to
submit my job and failed.
Best, Jiayi Liao

Hi Jiayi
As far as I know, there exist three ways:
Build the fat-application jar with dependencies using maven-shade-plugin or
maven-assembly-plugin.Copy the dependency jars to local ${FLINK_HOME}/lib
folder.Submit the job with-yt,--yarnship args command, please refer to
https://ci.apache.org/projects/flink/flink-docs-release-1.6/ops/cli.html#usage

Subject: What is the right way to add classpath?
Hi,all
My program needs some dependencies before it’s submitted to yarn. Like:
```
stream.filter(new FilterService()).print()
env.execute()
```
I use external dependency inFilterService, and the program reports
NoClassDefFoundError at
org.apache.flink.client.program.PackagedProgram.callMainMethod(PackagedProgram.java:529)
Now my solution is changing the bin/flink and add my classpath into it.
Any better ideas?
Thanks.
Best, Jiayi Liao
