Hadoop-2.2.0伪分布式和hbase-0.96.0-hadoop2伪分布式搭建

1. 部署

（1）主机名

gedit /etc/hostname  

master1

sudo gedit /etc/hosts 

127.0.0.1 master1

（2）SSH

sudo apt-get install ssh

mkdir /home/hadoop/.ssh

ssh-keygen -t rsa  

cat id_rsa.pub >> authorized_keys

ssh localhost

ssh master1

（3）环境变量

exportANT_HOME=/opt/apache-ant-1.9.3

exportMAVEN_HOME=/opt/apache-maven-3.0.5

exportFINDBUGS_HOME=/opt/findbugs-2.0.2

exportPATH=${ANT_HOME}/bin:${MAVEN_HOME}/bin:${FINDBUGS_HOME}/bin:$PATH

#jdk

exportJAVA_HOME=/opt/jdk1.7.0_45

exportJRE_HOME=/opt/jdk1.7.0_45

exportJRE_HOME=/opt/jdk1.7.0_45/jre

exportPATH=$JAVA_HOME/bin:$JRE_HOME/bin:$PATH

#hadoop

exportHADOOP_HOME=/opt/hadoop-2.2.0

exportHADOOP_CONF_DIR=${HADOOP_HOME}/etc/hadoop

exportPATH=$PATH:$HADOOP_HOME/bin:$HADOOP_HOME/sbin

#hbase

exportHBASE_HOME=/opt/hbase-0.96.0-hadoop2

exportPATH=$PATH:$HBASE_HOME/bin

（4）放置

/opt/jdk1.7.0_45

/opt/hadoop-2.2.0

/opt/hbase-0.96.0-hadoop2

（5）本地目录创建（根据下面的配置文件）

mkdir -p /data/tmp_hadoop /data/hdfs/nn   /data/hdfs/dn   /data/tmp_hbase   /data/yarn/local /data/yarn/logs/data/log/hadoop-hdfs /data/log/hadoop-yarn /data/log/hadoop-mapred
