Hi, Saurabh. It seems that you are hitting https://issues.apache.org/jira/browse/SPARK-26095 .
And, we disabled the parallel build via https://github.com/apache/spark/pull/23061 at 3.0.0. According to the stack trace in JIRA and PR description, `maven-shade-plugin` seems to be the root cause. For now, I'd like to recommend you to disable it because `Maven` itself warns you already. (You know that, right?) [INFO] --------------------------------[ pom > ]--------------------------------- > [WARNING] ***************************************************************** > [WARNING] * Your build is requesting parallel execution, but project * > [WARNING] * contains the following plugin(s) that have goals not marked * > [WARNING] * as @threadSafe to support parallel building. * > [WARNING] * While this /may/ work fine, please look for plugin updates * > [WARNING] * and/or request plugins be made thread-safe. * > [WARNING] * If reporting an issue, report it against the plugin in * > [WARNING] * question, not against maven-core * > [WARNING] ***************************************************************** > [WARNING] The following plugins are not marked @threadSafe in Spark > Project Parent POM: > [WARNING] org.scalatest:scalatest-maven-plugin:2.0.0 > [WARNING] Enable debug to see more precisely which goals are not marked > @threadSafe. > [WARNING] ***************************************************************** I respect `Maven` warnings.
