             Summary: NullPointerException when running Flink Nexmark tests on Streaming after switch to SDF based translation
                 Key: BEAM-11028
                 URL: https://issues.apache.org/jira/browse/BEAM-11028
             Project: Beam
          Issue Type: Test
          Components: runner-core, runner-flink, testing-nexmark
    Affects Versions: 2.25.0
            Reporter: Ismaël Mejía
            Assignee: Luke Cwik


When running Nexmark on Streaming mode with Flink locally via:
 
/gradlew :sdks:java:testing:nexmark:run \
      -Pnexmark.runner=":runners:flink:1.10" \
      -Pnexmark.args=" \
          --runner=FlinkRunner \
          --streaming=true \
          --suite=SMOKE \
          --manageResources=false \
          --monitorJobs=true \
          --enforceEncodability=true \
          --enforceImmutability=true"
 
I see the following error and get no results (this works ok in Beam 2.24.0)

I just wanted to tell you in case you want to take a look, this is happening in current master and also in 2.25.0 branch so I suppose is related to the recent changes. I have not issued a JIRA yet
