I am wondering if we could add an integration test to cover this. @faycheng

hi, @allencloud , i am afraid that i could not add integration test cases for this PR.
Actually, making a specific scene for verifying Endpoint cleanup works is too hard to me.
Sorry, maybe other genius contributors could help to do it.

That is all right. To be honest, this is indeed some kind of complex. @faycheng
