Hi Xiqian,
Thanks,Xiqian.I checked the Flink Home /lib directory  and found  i 
put  flink-cdc-pipeline-connector-mysql-3.1.jar,flink-cdc-pipeline-connector-doris-3.1.jar in
 /lib directory. I remove these two and go right.I think maybe jar conflicts. I 
had use flink-cdc 3.0 and  it go right


Regards,
Qijun

Hi Qijun,
 
&nbsp;
 
This error message usually implies that required dependencies were not met. 
Could you please confirm if you’ve placed all .jar files like this:
 
&nbsp;
  
Flink Home
 
/lib
 
mysql-connector-java-8.0.27.jar

… other pre-bundled jars
  
Flink CDC Home
 
/lib
 
flink-cdc-dist-3.1.jar (pre-bundled)

flink-cdc-pipeline-connector-mysql-3.1.jar

flink-cdc-pipeline-connector-doris-3.1.jar
   
&nbsp;
 
before executing ./flink-cdc.sh at Flink CDC Home.
