> Project: Flink
> Issue Type: Bug
> Components: Flink CDC
> Reporter: Flink CDC Issue Import
> Priority: Major
> Labels: github-import
>
> ### Search before asking
> - [X] I searched in the
> [issues|https://github.com/ververica/flink-cdc-connectors/issues) and found
> nothing similar.
> ### Flink version
> 1.14
> ### Flink CDC version
> 3.0.0
> ### Database and its version
> MySQL 5.7
> ### Minimal reproduce step
> Put `flink-sql-connector-tidb-cdc-3.0.0.jar`,
> `flink-sql-connector-mysql-cdc-3.0.0.jar` and
> `flink-sql-connector-mongodb-cdc-3.0.0.jar` into lib folder at Flink home
> (Flink 1.14 in my case], then create a MySQL CDC table and submit a simple
> query like `select * from mysql_cdc_table`, there would be an error:
> `java.io.InvalidClassException:
> com.ververica.cdc.connectors.shaded.com.fasterxml.jackson.databind.cfg.MapperConfig;
> incompatible types for field _mapperFeatures`
> It's caused by inconsistent jackson versions of the CDC connectors:
> - `flink-sql-connector-mongodb-cdc-3.0.0.jar`: 2.10.2
> - `flink-sql-connector-mysql-cdc-3.0.0.jar`: 2.13.2
> - `flink-sql-connector-tidb-cdc-3.0.0.jar`: 2.12.3
> ### What did you expect to see?
> All CDC connectors use the same jackson version.
> ### What did you see instead?
> Inconsistent jackson versions among the CDC connectors which conflicts with
> each other.
> ### Anything else?
> _No response_
> ### Are you willing to submit a PR?
> - [X] I'm willing to submit a PR!
