我遇到了一些問題，需要使用master和worker啓動Spark羣集。我在Ubuntu 16.04 LTS上下載並安裝了Hadoop 2.7.3和Spark 2.0.0。我做了一個的conf /從站我的奴隸的IP的文件，這是我spark-env.sh無法啓動apache spark獨立羣集
#!/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"
我使用start-master.sh開始主，這一切都OK。我嘗試運行工作人員時遇到了一些問題。
我試着：
(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)
隨着（1）E（2）從設備顯然開始，但在主站：8080它被未示出。使用（3）它拋出這個異常：

碩士和工人通過安裝使用橋接連接相同的Windows 10主機上的VMware虛擬機託管。
我也關閉了防火牆。
我該怎麼辦？
在此先感謝。
檢查您的主機是否可以訪問您的工作器，反之亦然。 – Ravikumar
