jmtd opened a new issue, #3845: URL: https://github.com/apache/incubator-heron/issues/3845
**Describe the bug** The very first example topology is broken with the latest version of the docker container (which, interestingly, is a micro version ahead of GitHub): 0.20.5-incubating (the example used in https://github.com/apache/incubator-heron/blob/master/website2/docs/getting-started-docker.md) **To Reproduce** Steps to reproduce the behavior: 1. `docker run -it --rm -d -p 8889:8889 -p 8888:8888 --name local-heron apache/heron:0.20.5-incubating supervisord --nodaemon` (note version: 0.20.5-incubating) 2. `docker exec -it local-heron bash -c "heron submit sandbox /heron/examples/heron-eco-examples.jar org.apache.heron.eco.Eco --eco-config-file /heron/examples/heron_wordcount.yaml"` 3. See error **Expected behavior** ``` … [2022-07-07 14:33:02 +0000] [INFO]: Successfully launched topology 'heron-simple-wordcount-topology' ``` **Actual behavior** ``` ;docker exec -it local-heron bash -c "heron submit sandbox /heron/examples/heron-eco-examples.jar org.apache.heron.eco.Eco --eco-config-file /heron/examples/heron_wordcount.yaml" [2022-07-07 14:38:15 +0000] [INFO]: Using cluster definition in /usr/local/heron/conf/sandbox Exception in thread "main" Cannot create property=spouts for JavaBean=org.apache.heron.eco.definition.EcoTopologyDefinition@45b9a632 in 'string', line 22, column 1: name: "heron-simple-wordcount-to ... ^ Can not set java.util.Map field org.apache.heron.eco.definition.EcoTopologyDefinition.spouts to java.util.ArrayList in 'string', line 49, column 3: - id: "spout-1" ^ at org.yaml.snakeyaml.constructor.Constructor$ConstructMapping.constructJavaBean2ndStep(Constructor.java:291) at org.yaml.snakeyaml.constructor.Constructor$ConstructMapping.construct(Constructor.java:172) at org.yaml.snakeyaml.constructor.Constructor$ConstructYamlObject.construct(Constructor.java:332) at org.yaml.snakeyaml.constructor.BaseConstructor.constructObjectNoCheck(BaseConstructor.java:230) at org.yaml.snakeyaml.constructor.BaseConstructor.constructObject(BaseConstructor.java:220) at org.yaml.snakeyaml.constructor.BaseConstructor.constructDocument(BaseConstructor.java:174) at org.yaml.snakeyaml.constructor.BaseConstructor.getSingleData(BaseConstructor.java:158) at org.yaml.snakeyaml.Yaml.loadFromReader(Yaml.java:491) at org.yaml.snakeyaml.Yaml.load(Yaml.java:416) at org.apache.heron.eco.parser.EcoParser.loadTopologyFromYaml(EcoParser.java:87) at org.apache.heron.eco.parser.EcoParser.parseFromInputStream(EcoParser.java:50) at org.apache.heron.eco.Eco.submit(Eco.java:75) at org.apache.heron.eco.Eco.main(Eco.java:163) Caused by: java.lang.IllegalArgumentException: Can not set java.util.Map field org.apache.heron.eco.definition.EcoTopologyDefinition.spouts to java.util.ArrayList at java.base/jdk.internal.reflect.UnsafeFieldAccessorImpl.throwSetIllegalArgumentException(UnsafeFieldAccessorImpl.java:167) at java.base/jdk.internal.reflect.UnsafeFieldAccessorImpl.throwSetIllegalArgumentException(UnsafeFieldAccessorImpl.java:171) at java.base/jdk.internal.reflect.UnsafeObjectFieldAccessorImpl.set(UnsafeObjectFieldAccessorImpl.java:81) at java.base/java.lang.reflect.Field.set(Field.java:780) at org.yaml.snakeyaml.introspector.PropertySubstitute.set(PropertySubstitute.java:105) at org.yaml.snakeyaml.constructor.Constructor$ConstructMapping.constructJavaBean2ndStep(Constructor.java:286) ... 12 more 2022-07-07 14:38:15.450 INFO - o.a.heron.eco.parser.EcoParser - main - Parsing eco config file 2022-07-07 14:38:15.453 INFO - o.a.heron.eco.parser.EcoParser - main - Not performing property substitution. 2022-07-07 14:38:15.453 INFO - o.a.heron.eco.parser.EcoParser - main - Not performing environment variable substitution. 2022-07-07 14:38:15.450 INFO - o.a.heron.eco.parser.EcoParser - main - Parsing eco config file 2022-07-07 14:38:15.453 INFO - o.a.heron.eco.parser.EcoParser - main - Not performing property substitution. 2022-07-07 14:38:15.453 INFO - o.a.heron.eco.parser.EcoParser - main - Not performing environment variable substitution.
