- 配置好时间同步
步骤
- 下载
Sqoop2
的安装包 - 解压安装包到
/usr/lib
目录下 - 修改
sqoop.sh
环境变量 - 修改
sqoop.properties
配置 - 导入第三方
jar
包 - 配置第三方
jar
包引用路径 - 修改
Ambari
上组件配置 - 验证配置是否正确
- 开启服务器
下载 Sqoop2 的安装包
下载地址:http://mirror.bit.edu.cn/apache/sqoop/1.99.7/
下载命令
cd ~
wget http://mirror.bit.edu.cn/apache/sqoop/1.99.7/sqoop-1.99.7-bin-hadoop200.tar.gz
解压安装包到 /usr/lib
目录下
解压 Sqoop2
压缩包
tar -xvf sqoop-<version>-bin-hadoop<hadoop-version>.tar.gz
移动到 /usr/lib/sqoop
目录
mv sqoop-<version>-bin-hadoop<hadoop version> /usr/lib/sqoop
修改 sqoop.sh 环境变量
编辑 /usr/lib/sqoop/bin/sqoop.sh
文件
sudo vim /usr/lib/sqoop/bin/sqoop.sh
找到 function sqoop_server_classpath_set
函数,将其中的环境变量改一下就可以了,如下:
function sqoop_server_classpath_set {
HADOOP_COMMON_HOME=${HADOOP_COMMON_HOME:-${HADOOP_HOME}/share/hadoop/common}
HADOOP_HDFS_HOME=${HADOOP_HDFS_HOME:-${HADOOP_HOME}/share/hadoop/hdfs}
HADOOP_MAPRED_HOME=${HADOOP_MAPRED_HOME:-${HADOOP_HOME}/share/hadoop/mapreduce}
HADOOP_YARN_HOME=${HADOOP_YARN_HOME:-${HADOOP_HOME}/share/hadoop/yarn}
将这些环境变量都注释掉,改为下面的内容即可:
function sqoop_server_classpath_set {
HDP=/usr/hdp/3.0.1.0-187
HADOOP_COMMON_HOME=$HDP/hadoop
HADOOP_HDFS_HOME=$HDP/hadoop-hdfs
HADOOP_MAPRED_HOME=$HDP/hadoop-mapreduce
HADOOP_YARN_HOME=$HDP/hadoop-yarn
修改 sqoop.properties 配置
修改 sqoop.properties
sudo vim /usr/lib/sqoop/conf/sqoop.properties
找到 org.apache.sqoop.submission.engine.mapreduce.configuration.directory
参数,如下:
org.apache.sqoop.submission.engine.mapreduce.configuration.directory=/etc/hadoop/conf/
根据集群实际信息将其改为下面的内容即可:
org.apache.sqoop.submission.engine.mapreduce.configuration.directory=/usr/hdp/3.1.0.0-78/hadoop/conf/
导入第三方 jar 包
mkdir /usr/lib/sqoop/extra
cp /var/lib/ambari-server/resources/mysql-jdbc-driver.jar /usr/lib/sqoop/extra/
cp -r /usr/lib/sqoop/extra/* /usr/lib/sqoop/server/lib/
cp -r /usr/lib/sqoop/extra/* /usr/lib/sqoop/shell/lib/
cp -r /usr/lib/sqoop/extra/* /usr/lib/sqoop/tools/lib/
配置第三方 jar 包引用路径
sudo vim ~/.bashrc
添加环境变量,如下:
export SQOOP_HOME=/usr/lib/sqoop
export SQOOP_SERVER_EXTRA_LIB=$SQOOP_HOME/extra
export PATH=$PATH:$SQOOP_HOME/bin
运行如下命令,使环境变量生效:
source ~/.bashrc
修改 Ambari 上组件配置
