-----------------------------------
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
