Hi @m3ngyang. Thanks for your PR.

I'm waiting for a kubernetes member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.

Thanks for helping with our quality.
I assume for looking at the changes you are trying to get our lint errors down.
If we don't clear all the errors in the directory and then mark the directory as clean then it is very easy for someone else to (re)introduce more lint errors in the directory.
Can you remove pkg/master from https://github.com/kubernetes/kubernetes/blob/master/hack/.golint_failures#L140?

[m3ngyang]

Do I need to fix all golint errors in pkg/master before removing it from golint_failures. There exists some other golint errors, such as exported functions/structs lacking comments. @cheftako

@m3ngyang Yes you would need to fix the remaining golint errors for pkg/master. However I think that is the right way to proceed.
