It appears to fork a JVM for every individual test (e.g. {{org.apache.spark.streaming.DurationSuite}}). When I tried it out on Jenkins, the tests [timed out after 2 hours|https://github.com/apache/spark/pull/3564#issuecomment-65349149]. > Parallelize execution of tests > ------------------------------ > > Key: SPARK-3431 > URL: https://issues.apache.org/jira/browse/SPARK-3431 > Project: Spark > Issue Type: Improvement > Components: Build > Reporter: Nicholas Chammas > > Running all the tests in {{dev/run-tests}} takes up to 2 hours. A common > strategy to cut test time down is to parallelize the execution of the tests. > Doing that may in turn require some prerequisite changes to be made to how > certain tests run. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
