#1357

[jessesuen]

I agree with @dtaniwaki comments. @zhujl1991 - If those are addressed we can merge it in.

Is it possible that the same issue breaks termination when retry is used? #1620

@alexec Is the e2e test flaky? https://github.com/argoproj/argo/pull/1369/commits we can see from here my commit 6f1e00f passed the e2e test while my latest one failed. But the only diff between the two commits is the revert of Gopkg.lock file.

[zhujl1991]

Hmm... Looks like the e2e test passed somehow. It was failed just now.

[alexec]

e2e tests are not 100% stable yet
