使用Mesos运行停靠的Spark打破了Mesos

Question

我试图使用Spark on Mesos在DC / OS上运行Jupyter Notebook docker（Ubuntu 16.04版本）。 Python输出了大量无用的错误消息，但在连接到容器并尝试从容器运行spark-submit作业后，我收到了很多关于连接问题的错误。

Spark驱动程序无法正确连接到Mesos，似乎在大多数情况下设置LIBPROCESS_IP就足够了。然而，在我的情况下使用它完全挂起了Mesos。

这就是我在docker容器中运行的内容：

export LIBPROCESS_ADVERTISE_IP=172.16.6.105; export SPARK_HOME=spark-2.3.2-bin-hadoop2.6; export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64; export MESOS_NATIVE_JAVA_LIBRARY=/usr/local/lib/libmesos.so; export LIBPROCESS_IP=172.19.0.4; ./spark-2.3.2-bin-hadoop2.6/bin/spark-submit --master mesos://leader.mesos:5050 --class org.apache.spark.examples.SparkPi https://downloads.mesosphere.com/spark/assets/spark-examples_2.11-2.0.1.jar 30

Spark驱动程序挂起这部分：

I0312 07:18:13.722151  3764 sched.cpp:232] Version: 1.2.3
I0312 07:18:13.732707  3758 sched.cpp:336] New master detected at [email protected]:5050
I0312 07:18:13.733749  3758 sched.cpp:352] No credentials provided. Attempting to register without authentication

在这一步中，Mesos挂起。根本无法访问UI，DCOS启动后检查显示错误。

我检查了Mesos日志，这就是我所看到的：

这一直在重复。当我停止驱动程序时，Mesos仍然坏了并且一直在输出这些消息：

因此，似乎Spark Driver使用Subscribe调用向Mesos发送垃圾邮件如此之快，以至于Mesos无法跟上它们的处理速度。试过Spark 2.3.2和2.4.0，结果相同。

我尝试将Spark连接到Spark Mesos Dispatcher，但是即使设置了这些LIBPROCESS变量，我也会遇到常见的连接错误：

有没有人有这样的问题？我该如何解决？

我使用docker compose在mesos上运行spark。我已经有了一个Docker图像，其中安装了Mesos并配置了mesos集群，例如，我确定了Master和worker。然后，我写了这些docker compose for master和slaves。他们没有错误地工作。
