------------------------------------
Summary: Kinesis connector doesn't shade jackson dependency
Key: FLINK-14896
URL:
https://issues.apache.org/jira/browse/FLINK-14896 Project: Flink
Issue Type: Bug
Components: Connectors / Kinesis
Affects Versions: 1.9.0
Environment: AWS EMR 5.28.0
Reporter: Michel Davit
flink-kinesis-connector depends on aws java sdk which is shaded to {{org.apache.flink.kinesis.shaded.com.amazonaws.}}
{{However, the aws sdk has a transitive dependency to jackson wich is not shaded in the artifact.}}
{{This creates problem when running flink on YARN: }}{{The aws sdk requires jackson-core v2.6 but hadoop pulls in 2.3. See [here|
https://github.com/apache/flink/blob/e7c11ed672013512e5b159e7e892b27b1ef60a1b/flink-yarn/pom.xml#L133].}}
{{If YARN uses the loads wrong jackson version from classpath. Jod fails with}}

The flink-kinesis-connector should do as other connectors: shade jackson or use the flink-shaded-jackson core dependency
