Marko A. Rodriguez commented on TINKERPOP-1271:
-----------------------------------------------
Can you try below please:
{code}
cd spark-gremlin/
mvn clean install -DskipIntegrationTests=false
{code}
That will run for about 10 minutes.
> SparkContext should be restarted if Killed and using Persistent Context

> Key: TINKERPOP-1271
> URL: https://issues.apache.org/jira/browse/TINKERPOP-1271
> Project: TinkerPop
> Issue Type: Bug
> Components: hadoop
> Affects Versions: 3.2.0-incubating, 3.1.2-incubating
> Reporter: Russell Spitzer
>
> If the persisted Spark Context is killed by the user via the Spark UI or is
> terminated for some other error the Gremlin Console/Server is left with a
> stopped Spark Context. This could be caught and the spark context recreated.
> Oddly enough if you simply wait the context will "reset" itself or possible
> get GC'd out of the system and everything works again.
