篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Hadoop2.6 HA + spark1.6完整搭建相关的知识，希望对你有一定的参考价值。

一、安装环境变量:

yum install gcc

yum install gcc-c++

yum install make

yum install autoconfautomake libtool cmake

yum install ncurses-devel

yum install openssl-devel

yum install git git-svn git-email git-gui gitk

安装protoc(需用root用户)

1 tar -xvf protobuf-2.5.0.tar.bz2

2 cd protobuf-2.5.0

3 ./configure --prefix=/opt/protoc/

4 make && make install

安装wget

sudo yum -y install wget

二、增加用户组

groupadd hadoop 添加一个组

useradd hadoop -g hadoop 添加用户

三、编译hadoop

mvn clean package -Pdist,native -DskipTests -Dtar

编译完的hadoop在 /home/hadoop/ocdc/hadoop-2.6.0-src/hadoop-dist/target 路径下

四、各节点配置hosts文件 vi/etc/hosts

10.1.245.244 master

10.1.245.243 slave1

10.1.245.242 slave2

命令行输入 hostname master

ssh到其他主机相应输入 hostName xxxx

五、各节点免密码登录：

各节点免密码登录

ssh-keygen -t rsa

cd /root/.ssh/

ssh-copy-id master

将生成的公钥id_rsa.pub 内容追加到authorized_keys（执行命令：cat id_rsa.pub >> authorized_keys）

时间等效性同步

ssh master date; ssh slave1 date;ssh slave2 date;

六、各节点hadoop路径下创建相应目录（namenode,datenode 等信息存放处）

Mkdir data

(在data路径下创建目录)

mkdir yarn

mkdir jn

mkdir current

(hadoop路径下)

mkdir name

(jn目录下)

mkdir streamcluster

七、Zookeeper配置:

Tar zxvf zookeeper-3.4.6.tar.gz

Cp zoo_sample.cfg zoo.cfg

修改zoo.cfg文件:

# 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/hadoop/ocdc/zookeeper-3.4.6/data

dataLogDir=/home/hadoop/ocdc/zookeeper-3.4.6/logs

# the port at which the clients will connect

clientPort=2183

# 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=master:2898:3898

server.2=slave1:2898:3898

server.3=slave2:2898:3898

在zookeeper目录下:

mkdir data

vi myid （写入id为1,）

拷贝zookeeper到各个目录下（将slave1中的myid改为2，slave2中的myid改为3....）

随后在 bin目录下逐个启动zookeeper

./zkServer.sh start

./zkServer.sh status (查看状态)

（需要注意的是在yarn-site.xml中

如果做HA 备用namenode服务器要修改为rm2）

mapred-site.xml

<value>master:10020</value>

</property>

<name>yarn.scheduler.maximum-allocation-mb</name>

</property>

<name>mapred.output.compression.type</name>

<value>BLOCK</value>

</property>

</configuration>

slaves

vi slaves

master1

slave1

slave2

随后将拷贝配置好的hadoop到各个服务器中

九、启动Hadoop各组件

启动jounalnode

./hadoop-daemon.sh start journalnode

进行namenode格式化

./hadoop 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，之后通过下面命令，启动namenode进程在namenode2上执行

sbin/hadoop-daemon.sh start namenode

完成主备节点同步信息

./hdfs namenode –bootstrapStandby

格式化ZK(在namenode1上执行即可, 这句命令必须手工打上，否则会报错)

./hdfs zkfc –formatZK

启动HDFS(在namenode1上执行)

./start-dfs.sh

启动YARN(在namenode1和namenode2上执行)

./start-yarn.sh

在namenode1上执行${HADOOP_HOME}/bin/yarn rmadmin -getServiceState rm1查看rm1和rm2分别为active和standby状态

我们在启动hadoop各个节点时，启动namenode和datanode，这个时候如果datanode的storageID不一样，那么会导致如下datanode注册不成功的信息：

这个时候，我们需要修改指定的datanode的current文件中的相应storageID的值，直接把它删除，这个时候，系统会动态新生成一个storageID，这样再次启动时就不会发生错误了。

查看端口是否占用

netstat -tunlp |grep 22

查看所有端口

netstat -anplut

十、spark搭建

修改spark-env..sh 增加如下参数(路径根据服务器上的路径修改)

HADOOP_CONF_DIR=/home/hadoop/ocdc/hadoop-2.6.0/etc/hadoop/

HADOOP_HOME=/home/hadoop/ocdc/hadoop-2.6.0/

SPARK_HOME=/home/hadoop/ocdc/spark-1.6.1-bin-hadoop2.6/

SPARK_EXECUTOR_INSTANCES=3

SPARK_EXECUTOR_CORES=7

SPARK_EXECUTOR_MEMORY=11G

SPARK_DRIVER_MEMORY=11G

SPARK_YARN_APP_NAME="asiainfo.Spark-1.6.0"

#SPARK_YARN_QUEUE="default"

MASTER=yarn-cluster

修改spark-default.conf文件 (路径根据服务器上的路径修改)

spark.master yarn-client

spark.speculation false

spark.sql.hive.convertMetastoreParquet false

spark.driver.extraClassPath /home/hadoop/ocdc/spark-1.6.1-bin-hadoop2.6/lib/mysql-connector-java-5.1.30-bin.jar:/home/hadoop/ocdc/spark-1.6.1-bin-hadoop2.6/lib/datanucleus-api-jdo-3.2.6.jar:/home/hadoop/ocdc/spark-1.6.1-bin-hadoop2.6/lib

/datanucleus-core-3.2.10.jar:/home/hadoop/ocdc/spark-1.6.1-bin-hadoop2.6/lib/datanucleus-rdbms-3.2.9.jar:/home/hadoop/ocdc/spark-1.6.1-bin-hadoop2.6/lib/ojdbc14-10.2.0.3.jar

Hadoop监控页面(根据yarn-site.xml的参数yarn.resourcemanager.webapp.address.rm1中配置的端口决定的):
