单机基于docker搭建hadoop2.7.1 spark1.7 高可用集群

获取ubuntu镜像

sudo docker pull ubuntu
　　分别下载 spark1.7 hadoop2.7.1 scala1.1 zookeeper3.4.6 jdk1.8 解压后放置本地文件夹用于挂载到容器中

并在文件夹下创建文件

authorized_keyshosts
　　本例目录使用/home/docker/config






启动容器

　　

sudo docker run --name installspark -v /home/docker/config/:/config -it ubuntu:14.04



　　


安装

　　启动后在容器内/config文件夹下能够看到放置的安装文件

安装jdk,scala :

vim ~/.bashrc追加:

/usr/sbin/sshd
cat /config/hosts > /etc/hosts
cat /config/authorized_keys > /root/.ssh/authorized_keys
export JAVA_HOME=/usr/lib/jvm/java-8-sun
export PATH=${JAVA_HOME}/bin:$PATH
export HADOOP_HOME=/opt/hadoop
export PATH=${HADOOP_HOME}/bin:$PATH
export SCALA_HOME=/opt/scala
export PATH=${SCALA_HOME}/bin:$PATH
export SPARK_HOME=/opt/spark
export PATH=${SPARK_HOME}/bin:$PATH
　　拷贝 spark/hadoop/zookeeper到/opt下

启动hadoop集群


在dnzk1/dnzk2/dnzk3上启动zookeeper和 hadoop journal

/opt/zookeeper/bin/zkServer.sh start
/opt/hadoop/sbin/hadoop-daemon.sh start journalnode

在nn1上格式化zookeeper启动和format hadoop

/opt/hadoop/bin/hdfs namenode -formatscp -r /opt/hadoop/namenode/ nn2:/opt/hadoop/或/opt/hadoop/bin/hdfs namenode -bootstrapStandby

/opt/hadoop/bin/hdfs zkfc -formatZK

/opt/hadoop/sbin/start-dfs.sh



在rm1上启动yarn/opt/hadoop/sbin/start-yarn.sh

在rm2上启动/opt/hadoop/sbin/yarn-daemon.sh start resourcemanager

　　启动spark
　　/opt/spark/sbin/start-all.sh
