Hi @sakitha ,

 

What version of CDH/HDP/CDP are you using? If you are using Cloudera Manager (CM), please check the MirrorMaker parameter values for presence of any "}" characters. The error, as shown, indicates there is something wrong with Whitelist parameter or the like.

Hi @sakitha 

 

Seems to be a known issue. 

Is the topic whitelist is set to " * " ?  Can you please try with dot  - " .*" 

 

Let us know if that works for you.
