关于准备工作我这里就不一一写出来了，总结一下有主机名，ip，主机名和ip的映射关系，防火墙，ssh免密码，jdk的安装及环境变量的设置。

安装zookeeper到 h5、h6、h7上面

修改 /home/zookeeper-3.4.8/conf的zoo_sample.cfg

cp zoo_sample.cfg zoo.cfg

# The number of milliseconds of each tick

tickTime=2000

# The number of ticks that the initial

# synchronization phase can take

initLimit=10

# The number of ticks that can pass between

# sending a request and getting an acknowledgement

syncLimit=5

# the directory where the snapshot is stored.

# do not use /tmp for storage, /tmp here is just

# example sakes.

dataDir=/home/zookeeper-3.4.8/data

# the port at which the clients will connect

clientPort=2181

# the maximum number of client connections.

# increase this if you need to handle more clients

#maxClientCnxns=60

# Be sure to read the maintenance section of the

# administrator guide before turning on autopurge.

# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance

# The number of snapshots to retain in dataDir

#autopurge.snapRetainCount=3

# Purge task interval in hours

# Set to "0" to disable auto purge feature

#autopurge.purgeInterval=1

server.1=h5:2888:3888

server.2=h6:2888:3888

server.3=h7:2888:3888

创建 data文件夹和在里面创建文件myid 并写入数字1

touch data/myid

echo 1 > data/myid

拷贝整个zookeeper到另外两个节点上

scp -r /home/zookeeper-3.4.8 h6:/home/

scp -r /home/zookeeper-3.4.8 h7:/home/

其他两个节点的myid 修改为 2 3

安装hadoop

/home/hadoop-2.7.2/etc/Hadoop

hadoop-env.sh：

export JAVA_HOME=/home/jdk

core-site.xml：

<name>fs.defaultFS</name>

Slaves：

然后拷贝到其他节点

scp -r hadoop-2.7.2 h2:/home/ 等等

这个地方说明一下 yarn 的HA 是在 h3和h4 上面

启动顺序

###注意：严格按照下面的步骤

启动zookeeper集群

[root@h6 ~]# cd /home/zookeeper-3.4.8/bin/

[root@h6 bin]# ./zkServer.sh start

H5 h6 h7 都一样

[root@h6 bin]# ./zkServer.sh status

查看状态

启动journalnode

[root@h5 bin]# cd /home/hadoop-2.7.2/sbin/

[root@h5 sbin]# ./hadoop-daemons.sh start journalnode

h5: starting journalnode, logging to /home/hadoop-2.7.2/logs/hadoop-root-journalnode-h5.out

h7: starting journalnode, logging to /home/hadoop-2.7.2/logs/hadoop-root-journalnode-h7.out

h6: starting journalnode, logging to /home/hadoop-2.7.2/logs/hadoop-root-journalnode-h6.out

[root@h5 sbin]# jps

2420 JournalNode

2309 QuorumPeerMain

2461 Jps

[root@h5 sbin]# ^C

格式化HDFS

在h1上执行命令:

hdfs namenode -format

格式化后会在根据core-site.xml中的hadoop.tmp.dir配置生成个文件

拷贝tmp 到 h2

[root@h1 hadoop-2.7.2]# scp -r tmp/ h2:/home/hadoop-2.7.2/

4. 格式化ZK(在h1上执行即可)

[root@h1 hadoop-2.7.2]# hdfs zkfc -formatZK

5. 启动HDFS(在h1上执行)

[root@h1 hadoop-2.7.2]# sbin/start-dfs.sh

16/02/25 05:01:14 WARN hdfs.DFSUtil: Namenode for ns1 remains unresolved for ID null. Check your hdfs-site.xml file to ensure namenodes are configured properly.

16/02/25 05:01:14 WARN hdfs.DFSUtil: Namenode for ns2 remains unresolved for ID null. Check your hdfs-site.xml file to ensure namenodes are configured properly.

16/02/25 05:01:14 WARN hdfs.DFSUtil: Namenode for ns3 remains unresolved for ID null. Check your hdfs-site.xml file to ensure namenodes are configured properly.

Starting namenodes on [h1 h2 masters masters masters]

masters: ssh: Could not resolve hostname masters: Name or service not known

h2: starting namenode, logging to /home/hadoop-2.7.2/logs/hadoop-root-namenode-h2.out

h1: starting namenode, logging to /home/hadoop-2.7.2/logs/hadoop-root-namenode-h1.out

h5: starting datanode, logging to /home/hadoop-2.7.2/logs/hadoop-root-datanode-h5.out

h7: starting datanode, logging to /home/hadoop-2.7.2/logs/hadoop-root-datanode-h7.out

h6: starting datanode, logging to /home/hadoop-2.7.2/logs/hadoop-root-datanode-h6.out

Starting journal nodes [h5 h6 h7]

h5: journalnode running as process 2420. Stop it first.

h6: journalnode running as process 2885. Stop it first.

h7: journalnode running as process 2896. Stop it first.

Starting ZK Failover Controllers on NN hosts [h1 h2 masters masters masters]

masters: ssh: Could not resolve hostname masters: Name or service not known

h2: starting zkfc, logging to /home/hadoop-2.7.2/logs/hadoop-root-zkfc-h2.out

h1: starting zkfc, logging to /home/hadoop-2.7.2/logs/hadoop-root-zkfc-h1.out

[root@h1 hadoop-2.7.2]#

6. 启动YARN(是在h3上执行start-yarn.sh，把namenode和resourcemanager分开是因为性能问题，因为他们都要占用大量资源，所以把他们分开了，他们分开了就要分别在不同的机器上启动)

[root@h3 sbin]# ./start-yarn.sh

[root@h4 sbin]# ./yarn-daemons.sh start resourcemanager

验证：

http://192.168.128.11:50070

Overview 'h1:9000' (active)

http://192.168.128.12:50070

Overview 'h2:9000' (standby)

上传文件

[root@h4 bin]# hadoop fs -put /etc/profile /profile

[root@h4 bin]# hadoop fs -ls

ls: `.': No such file or directory

[root@h4 bin]# hadoop fs -ls /

Found 1 items

-rw-r--r-- 3 root supergroup 1814 2016-02-26 19:08 /profile

[root@h4 bin]#

杀死h1

[root@h1 sbin]# jps

2480 NameNode

2868 Jps

2775 DFSZKFailoverController

[root@h1 sbin]# kill -9 2480

[root@h1 sbin]# jps

2880 Jps

2775 DFSZKFailoverController

[root@h1 sbin]# hadoop fs -ls /

Found 1 items

-rw-r--r-- 3 root supergroup 1814 2016-02-26 19:08 /profile

此时 h2 变为active

手动启动 h1的 namenode

[root@h1 sbin]# ./hadoop-daemon.sh start namenode

starting namenode, logging to /home/hadoop-2.7.2/logs/hadoop-root-namenode-h1.out

[root@h1 sbin]# hadoop jar /home/hadoop-2.7.2/s

观察 h1 状态为standby

验证yarn

[root@h1 sbin]# hadoop jar /home/hadoop-2.7.2/share/hadoop/mapreduce/hadoop-mapreduce-examples-2.7.2.jar wordcount /profile /out
