------------------------------------
Summary: Incorrect placeholder used in MySqlDataSourceFactory
exception message
Key: FLINK-39916
URL: https://issues.apache.org/jira/browse/FLINK-39916
Project: Flink
Issue Type: Bug
Components: Flink CDC
Affects Versions: cdc-3.5.0
Reporter: XiaodongHuan
In MySqlDataSourceFactory, the exception message uses "{}" as a placeholder
inside String.format(...).
Current code:
throw new IllegalArgumentException(
String.format(
"Only \"snapshot\" of MySQLDataSource StartupOption is
supported in BATCH pipeline, but actual MySQLDataSource StartupOption is {}.",
startupOptions.startupMode));
Expected:
The actual startup mode should be included in the exception message.
Suggested fix:
Replace "{}" with "%s":
