[jira] [Commented] (SLIDER-264) Test runners to fail fast if app is already finished

["Steve Loughran (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SLIDER-264?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14079133#comment-14079133 ] 

Steve Loughran commented on SLIDER-264:
---------------------------------------

there's a problem here in that YARN may list a previous test run in the app list, so there is already 1+ instance in the finished state. The runner will have to enum all existing instances and IDs, and fail fast if a new {{FINISHED}} instance appears

> bq. "the test logic might be able to be improved as it was repeatedly waiting for Accumulo to start when it was already in the FINISHED state. We might be able to short-circuit the test logic to fail faster in this case."
> the test runner may be spinning until started or timeout, when it should bail when finished.
