解压安装

cd ~
tar -zxvf hadoop-2.7.3.tar.gz
mv  hadoop-2.7.3  hadoop

配置环境变量

vi ~/.bash_profile
export JAVA_HOME=/wls/oracle/jdk
export SCALA_HOME=/wls/oracle/scala
export ZOOKEEPER_HOME=/wls/oracle/zookeeper
export HADOOP_HOME=/wls/oracle/hadoop
export HBASE_HOME=/wls/oracle/hbase
export SPARK_HOME=/wls/oracle/spark   

export PATH=$PATH:$HOME/bin:$JAVA_HOME/bin:$SCALA_HOME/bin:$SPARK_HOME/bin:$ZOOKEEPER_HOME/bin:$HADOOP_HOME/bin:$HBASE_HOME/bin
export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar   

export PATH　CLASSPATH JAVA_HOME  SCALA_HOME  ZOOKEEPER_HOME HADOOP_HOME SPARK_HOME

hadoop配置更改

hadoop相关的配置都在$HADOOP_HOME/etc/hadoop目录下,hadoop集群搭建主要涉及如下配置文件的变更

hadoop-env.sh

hadoop-env.sh文件只需要改动JAVA_HOME为具体的路径即可

 export JAVA_HOME=/wls/oracle/jdk

重复启停异常后，可以尝试删除

rm -f /wls/oracle/bigdata/hadoop/tmp/dfs/data/current/VERSION

hbase安装

解压安装

tar -zxvf hbase-1.2.4-bin.tar.gz
mv hbase-1.2.4-bin hbase

环境变量

vi ~/.bash_profile
export JAVA_HOME=/wls/oracle/jdk
export SCALA_HOME=/wls/oracle/scala
export ZOOKEEPER_HOME=/wls/oracle/zookeeper
export HADOOP_HOME=/wls/oracle/hadoop
export HBASE_HOME=/wls/oracle/hbase
export SPARK_HOME=/wls/oracle/spark   

export PATH=$PATH:$HOME/bin:$JAVA_HOME/bin:$SCALA_HOME/bin:$SPARK_HOME/bin:$ZOOKEEPER_HOME/bin:$HADOOP_HOME/bin:$HBASE_HOME/bin

export PATH　CLASSPATH JAVA_HOME  SCALA_HOME  ZOOKEEPER_HOME HADOOP_HOME SPARK_HOME

配置

hbase需要修改的配置主要包含如下文件

hbase-env.sh
hbase-site.xml
regionservers

hbase-env.sh

hbase-env.sh文件增加JAVA_HOME的配置即可

export JAVA_HOME=/wls/oracle/jdk
