我正在尝试使用docker和zookeeper模拟一个多节点mesos集群，并尝试在其上运行一个简单的（py）spark作业。这些docker容器和pyspark脚本都在同一台机器上运行。但是，当我执行spark脚本时，它挂起在：

mesos从机不断输出：

mesos主docker映像是用以下dockerfile构建的

FROM ubuntu:14.04

ENV MESOS_V 0.24.0

# update

RUN apt-get update
RUN apt-get upgrade -y

# dependencies

RUN apt-get install -y wget openjdk-7-jdk build-essential python-dev python-boto libcurl4-nss-dev libsasl2-dev maven libapr1-dev libsvn-dev

# mesos

RUN wget http://www.apache.org/dist/mesos/${MESOS_V}/mesos-${MESOS_V}.tar.gz
RUN tar -zxf mesos-*.tar.gz
RUN rm mesos-*.tar.gz
RUN mv mesos-* mesos
WORKDIR mesos
RUN mkdir build
RUN ./configure
RUN make
RUN make install

RUN ldconfig

EXPOSE 5050

ENTRYPOINT ["/bin/bash"]

我手动执行 mesos-master 命令：

LIBPROCESS_IP=${MASTER_IP} mesos-master --registry=in_memory --ip=${MASTER_IP} --zk=zk://172.17.0.75:2181/mesos --advertise_ip=${MASTER_IP}

mesos从属docker映像是使用相同的dockerfile构建的，只是暴露了端口5051。然后在其容器中运行以下命令：

LIBPROCESS_IP=172.17.0.72 mesos-slave --master=zk://172.17.0.75:2181/mesos

pyspark脚本是：

import os
import pyspark

src = 'file:///{}/README.md'.format(os.environ['SPARK_HOME'])

leader_ip = '172.17.0.75'
conf = pyspark.SparkConf()
conf.setMaster('mesos://zk://{}:2181/mesos'.format(leader_ip))
conf.set('spark.executor.uri', 'http://d3kbcqa49mib13.cloudfront.net/spark-1.5.0-bin-hadoop2.6.tgz')
conf.setAppName('my_test_app')

sc = pyspark.SparkContext(conf=conf)

lines = sc.textFile(src)
words = lines.flatMap(lambda x: x.split(' '))
word_count = (words.map(lambda x: (x, 1)).reduceByKey(lambda x, y: x+y))
print(word_count.collect())

以下是pyspark脚本的完整输出：
