搭建hive-1.2.2和hadoop2.7.7单机模式

hive依赖hadoop环境。

第一步，搭建hadoop环境

下载：hadoop-2.7.7下载

解压，拷贝到安装目录：注意自己的目录

tar -zxvf hadoop-2.7.7.tar.gz
mv hadoop-2.7.7 hadoop
cp -R hadoop /user/local/soft

配置hadoop环境变量

JAVA_HOME=/usr/jdk
JRE_HOME=/usr/jdk/jre
CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib
PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin
export PATH JAVA_HOME CLASSPATH

export HADOOP_PREFIX=/usr/local/soft/hadoop
export HADOOP_HOME=$HADOOP_PREFIX
export HADOOP_MAPRED_HOME=$HADOOP_PREFIX
export HADOOP_COMMON_HOME=$HADOOP_PREFIX
export HADOOP_HDFS_HOME=$HADOOP_PREFIX
export YARN_HOME=$HADOOP_PREFIX
export HADOOP_COMMON_LIB_NATIVE_DIR=$HADOO_PREFIX/lib/native
export HADOOP_INSTALL=$HADOOP_PREFIX
export PATH=$PATH:$HADOOP_PREFIX/bin:$HADOOP_PREFIX/sbin

安装无登录SSH

yum install openssh-server
#一直点就行
ssh-keygen -t rsa
#验证
ssh localhost

hadoop启动配置

配置hadoop_env.sh的jdk

# The java implementation to use.
export JAVA_HOME=/usr/jdk

配置 core-site.xml

 cd /usr/local/soft/hadoop/etc/hadoop/
 vi core-site.xml
