-------------------------------------
Summary: JsonMappingException in DynamoDBStreamsSchema
Key: FLINK-11547
URL: https://issues.apache.org/jira/browse/FLINK-11547
Project: Flink
Issue Type: Bug
Components: Kinesis Connector
Affects Versions: 1.8.0
Reporter: Devin Thomson
Attachments: full_flink_trace.txt
If DynamoDBStreamsSchema is used as the deserializer for
FlinkDynamoDBStreamsConsumer, an exception occurs during deserialization of a
record. The stack trace is attached.
This is a blocker for using DynamoDBStreamsSchema, but can be worked around by
implementing a custom deserializer. The issue appears to be due to the usage of
vanilla ObjectMapper:
{code:java}
private static final ObjectMapper MAPPER = new ObjectMapper();
{code}
When it should be using the appropriate mix-ins offered by the dynamodb stream
adapter library:
{code:java}
private static final ObjectMapper MAPPER = new RecordObjectMapper();
{code}
This appears to resolve the issue, I tested by using my own deserializer
implementation.
