我有一些问题，以启动一个主Spark集群和工人。我在ubuntu16.04 lts上下载并安装了hadoop2.7.3和spark2.0.0。我用我的slave的ip创建了一个conf/slaves文件，这是我的spark-env.sh

# !/usr/bin/env #bash
export SPARK_DIST_CLASSPATH=$(hadoop classpath)
export SPARK_WORKER_CORES=2
export SPARK_MASTER_IP=192.168.1.6
export SPARK_LOCAL_IP=192.168.1.6
export SPARK_YARN_USER_ENV="JAVA_HOME=/usr/lib/jvm/java-8-oracle/jre"

我用start-master.sh启动了master，一切正常。我试着跑工人时遇到了一些问题。
我试过：

(1) - start-slave.sh spark://192.168.1.6:7077 (from worker)
(2) - start-slaves.sh (from master)
(3) - ./bin/spark-class org.apache.spark.deploy.worker.Worker spark://192.168.1.6:7077 (from worker)

在（1）e（2）中，从机显然已启动，但处于master:8080 it 没有显示。使用（3）会引发以下异常：

16/08/31 14:17:03 INFO worker.Worker: Connecting to master master:7077...
16/08/31 14:17:03 WARN worker.Worker: Failed to connect to master master:7077

16/08/31 14:17:40 ERROR worker.Worker: All masters are unresponsive! Giving up.

主进程和工作进程由使用桥接连接安装在同一Windows10主机上的VMWareVM托管。
我还禁用了防火墙。
我能做什么？？
提前谢谢。
