centos6 hadoop安裝

首先得安裝jdk(不懂看上面)

其次要安裝zookeeper(不懂看上面)

1、安裝jdk

2、下載hadoop-3.0.2，解壓

3、配置環境變量：

export HADOOP_HOME=/data/hadoop-3.0.2
export HADOOP_INSTALL=$HADOOP_HOME
export HADOOP_MAPRED_HOME=$HADOOP_HOME
export HADOOP_COMMON_HOME=$HADOOP_HOME
export HADOOP_HDFS_HOME=$HADOOP_HOME
export YARN_HOME=$HADOOP_HOME
export HADOOP_COMMON_LIB_NATIVE_DIR=$HADOOP_HOME/lib/native
export PATH=$PATH:$HADOOP_HOME/sbin:$HADOOP_HOME/bin

4、重啓環境變量

source /etc/profile

5、查看是否配置成功

[root@liu hadoop-3.0.2]# hadoop
Usage: hadoop [OPTIONS] SUBCOMMAND [SUBCOMMAND OPTIONS]
 or    hadoop [OPTIONS] CLASSNAME [CLASSNAME OPTIONS]
  where CLASSNAME is a user-provided Java class

  OPTIONS is none or any of:

buildpaths                       attempt to add class files from build tree
--config dir                     Hadoop config directory
--debug                          turn on sh
