Description

We cannot run two experiments with the same name. Take experimentIT.java as an example, the frontend E2E testcase will create an experiment named "experiment-e2e-test". If we run this testcase twice, the workbench just shows an "experiment-e2e-test" rather than two.

The root cause is that the K8sSubmitter will create two PODs for an "experiment-e2e-test". The names of these two PODs are "experiment-e2e-test-ps-0" and "experiment-e2e-test-worker-0". Hence, when we try to create the second "experiment-e2e-test", K8sSubmitter will throw an exception due to duplicate POD names.

 

To reproduce the bug:

 

// Step1: Run workbench on port 8080
// Step2: 
cd submarine-cloud-v2

// Step3: Create "experiment-e2e-test" twice
./hack/run_frontend_e2e.sh experimentIT
./hack/run_frontend_e2e.sh experimentIT

// Step4: Check Workbench: only an "experiment-e2e-test" exists => BUG!
