 Review comment:
   @lei-xia Yes 3 commits are for one issue. I will combine them into one commit and create another pull request. Other one is just for deleting the logs. I can create a separate issue for that. I already confirmed this log removal part with Junkai. @dasahcc can you please have a look and confirm it again.
   
   Thanks.
