open-falcon hadoop 搭建

本文主要是介绍open-falcon hadoop 搭建，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

目的

部署 hadoop

说明

Hadoop是一个用Java编写的Apache开源框架
允许使用简单的编程模型跨计算机集群分布式处理大型数据集
Hadoop框架工作的应用程序在跨计算机集群提供分布式存储和计算的环境中工作
Hadoop旨在从单个服务器扩展到数千个机器，每个都提供本地计算和存储

服务器与角色

角色	服务器	服务器	服务器	配置
	ns-yun-020022	ns-yun-020023	ns-yun-020024
zookeeper	Y	Y	Y
nameNode		Y	Y	hdfs-site.xml
dataNode	Y	Y	Y
resourceManager		Y	Y	yarn-site.xml
nodeManager	Y	Y	Y
journamNode	Y	Y	Y
zkFC		Y	Y

安装

解压

tar xf /usr/src/falcon-src/hadoop/hadoop-2.10.0.tar.gz -C /apps/svr/
ln -s hadoop-2.10.0 hadoop
mkdir -p /apps/svr/hadoop/tmp  /apps/svr/hadoop/hadoopdata/dfs/{name,data,journaldata}

系统环境

HADOOP_HOME=/apps/svr/hadoop/
PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin:$ZOOKEEPER_HOME/bin:$HADOOP_HOME/bin:$HADOOP_HOME/sbin
export  JAVA_HOME JRE_HOME CLASS_PATH  PATH USER LOGNAME MAIL HOSTNAME HISTSIZE HISTCONTROL ZOOKEEPER_HOME HADOOP_HOME

建议在每个机器上 /etc/hosts 中添加 IP 主机名对应信息
就算有 DNS 服务器支持也建议添加 IP 域主机名字信息 example

1.1.1.1    ns-yun-020022.133.com
1.1.1.2    ns-yun-020023.133.com
1.1.1.3    ns-yun-020024.133.com

否则启动 HADOOP 时会遇到一个 ip=1.1.1.1 hostname=1.1.1.1 及 hadoop datanode Datanode denied communication with namenode because hostname cannot be resolved 错误的错误

hadoop 配置

JAVA 环境, 修改 /apps/svr/hadoop-2.10.0/etc/hadoop/hadoop-env.sh

export JAVA_HOME=/apps/svr/java

修改集群主配置 /apps/svr/hadoop/etc/hadoop/core-site.xml

启动集群

检测当前 zookeeper 连接
正常集群中每个服务器都启动了下面的服务

[root@ns-yun-020022 hadoop]# jps
144379 QuorumPeerMain
152910 Jps

启动 jounalNode ( 22,23,24 都需要执行)

[root@ns-yun-020022 hadoop]# hadoop-daemon.sh start journalnode
starting journalnode, logging to /apps/svr/hadoop-2.10.0/logs/hadoop-root-journalnode-ns-yun-020022.133.com.out[root@ns-yun-020022 hadoop]# jps
153046 Jps
152967 JournalNode    <--- 这里启动了
144379 QuorumPeerMain

格式化 nameNode 只需要在一个节点上执行

[root@ns-yun-020022 hadoop]# hadoop namenode -format

复制数据到其他服务器

cd /apps/svr/hadoop-2.10.0
scp -r  hadoopdata  ns-yun-020023:`pwd`/.
scp -r  hadoopdata  ns-yun-020024:`pwd`/.
