------------------------------------
Parent: SUBMARINE-949
Issue Type: Sub-task (was: Bug)
> Cannot run two experiments with the same name
> ---------------------------------------------
>
> Key: SUBMARINE-880
> URL: https://issues.apache.org/jira/browse/SUBMARINE-880
> Project: Apache Submarine
> Issue Type: Sub-task
> Components: experiment
> Reporter: Kai-Hsun Chen
> Assignee: Kai-Hsun Chen
> Priority: Major
> Labels: pull-request-available
> Fix For: 0.6.0
>
>
> We cannot run two experiments with the same name. Take
> [experimentIT.java|https://github.com/apache/submarine/blob/master/submarine-test/test-e2e/src/test/java/org/apache/submarine/integration/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:
>
> {code:java}
> // 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!
> {code}
