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.

Regards,

Alex Akulov

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.
