使用Mesos运行dockered Spark会破坏Mesos

Question

我试图使用Mesos上的Spark在DC/OS上运行Jupyter Notebook docker(Ubuntu 16.04版本)。Python输出了许多无用的错误消息，但在连接到容器并尝试从容器运行spark-submit作业后，我收到了许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，在我的例子中，使用它完全挂起了Mesos。

这是我在docker容器中运行的：

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 driver挂在此部件上：

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 master@172.16.6.103:5050
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 poststart检查会显示错误。

我检查了Mesos日志，下面是我看到的：

这一过程一直在重复。当我停止驱动程序时，Mesos仍然是坏的，并且一直在输出这些消息：

所以看起来Spark Driver正在向Mesos发送垃圾邮件，订阅调用的速度太快，以至于Mesos无法跟上处理它们的步伐。尝试了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，我也得到了常见的连接错误：

有没有人有这样的问题？我该怎么解决它呢？

Answer 1

我使用docker compose在mesos上运行了spark。我已经有了一个安装了Mesos的docker镜像，并配置了mesos集群，例如，我确定了Master和workers。然后，我写了这些docker compose for master and slaves。他们毫无差错地工作。

作曲母版：

version: '3.7'
services:
  master:
   image: ubuntu_mesos_spark
   command: bash -c "sleep 40; /home/mesos-1.7.0/build/bin/mesos-master.sh --ip=150.20.11.136 --work_dir=/var/run/mesos --hostname=x.x.x.x"  ##hostname : IP of the master node
   restart: always
   network_mode: host
   environment:
    - MESOS_HOSTNAME="150.20.11.136"
    - MESOS_QUORUM=1
    - MESOS_LOG_DIR=/var/log/mesos
   expose:

    - 4040
    - 7077
    - 8080
   ports:
    - 5050:5050
    - 4040:4040
    - 7077:7077
    - 8080:8080

编写从属程序：

      --systemd_enable_support=false"
      restart: always

我希望这是有用的。
