Stephen Mallette updated TINKERPOP-2436:
----------------------------------------
Issue Type: Improvement (was: Bug)
> The gremlin server starts even if all graphs instantiation has failed
> ---------------------------------------------------------------------
>
> Key: TINKERPOP-2436
> URL: https://issues.apache.org/jira/browse/TINKERPOP-2436
> Project: TinkerPop
> Issue Type: Improvement
> Components: server
> Affects Versions: 3.4.8
> Reporter: Nicolas Trangosi
> Priority: Major
>
> Sometimes the gremlin server fails to open the graph due to backend failure.
> In this case, gremlin server starts even if could not serve any request as
> gremlin-groovy GremlinScriptEngine is not initialized. I think that in this
> case, gremlin server should stop (and be restarted in a kubernates cluster)
> {{8 Oct 2020 12:35:51,923 8660 [gremlin-server-exec-1] ERROR
