Yarn application undefined created by dr.who

Hi.

I have a question regarding yarn application.

As shown in the snapshot, hundreds of undefined yarn applications are created by dr.who every time. I never created that kind of jobs and I think they are created automatically by somehow but I don't know why.

Could you please advise that this happens in normal or not? If not, how can i fix it?

@Sungwoo Park: This is not normal and there is a security breach in your environment.
