Hi devs, I've found bunch of test failures (intermittently) in both CI build for master branch as well as PR builder (only checked for mine) yesterday. I just filed issues which I observed, but I guess there's more as I only checked my PR.
https://issues.apache.org/jira/browse/SPARK-29129 https://issues.apache.org/jira/browse/SPARK-29130 https://issues.apache.org/jira/browse/SPARK-29131 https://issues.apache.org/jira/browse/SPARK-29132 https://issues.apache.org/jira/browse/SPARK-29133 https://issues.apache.org/jira/browse/SPARK-29134 https://issues.apache.org/jira/browse/SPARK-29135 https://issues.apache.org/jira/browse/SPARK-29136 https://issues.apache.org/jira/browse/SPARK-29137 https://issues.apache.org/jira/browse/SPARK-29138 https://issues.apache.org/jira/browse/SPARK-29139 https://issues.apache.org/jira/browse/SPARK-29140 Other than that, there're another lots of failures with below message: java.util.concurrent.ExecutionException: java.lang.IllegalStateException: > Cannot call methods on a stopped SparkContext. Even some of them above might be affected as well. I couldn't check whether these issues have been resolved (not for PR builder as these failures were yesterday, but for master build) so any helps are appreciated. Thanks, Jungtaek Lim (HeartSaVioR)
