Re: What is the right way to add classpath?


Hi Jiayi

As far as I know, there exist three ways:
  1. Build the fat-application jar with dependencies using maven-shade-plugin or maven-assembly-plugin.
  2. Copy the dependency jars to local ${FLINK_HOME}/lib  folder.
  3. 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 in FilterService, 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.
