Apache Spark导致Tomcat正常关闭

时间：2015-12-09 13:41:50

标签： tomcat apache-spark tomcat7

Tomcat版本：7.0.47

我有一个使用Apache Spark的Web应用程序。我的Web应用程序充当Apache spark驱动程序。

当远程独立spark组件不可用时，Spark上下文将关闭并显示日志org.apache.spark.util.Utils - Shutdown hook called

这种情况发生后Tomcat也开始优雅地关闭。我在tomcat中看到的唯一日志是[exec] Result: 50

当火花调用它关闭时，Tomcat关闭的原因是什么？

如果使用IP地址代替主机名，则在 SparkConf 中设置主控时，使用 spark：// hostname：7077 作为spark master。

我遇到了同样的问题，它通过在spark master中使用主机名而不是使用IP地址来解决。
