HDP 3.1.0 集成 Sqoop2

环境

  • 由三台主机组成的 HDP 3.1.0 集群
  • 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

1
2
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

1
tar -xvf sqoop-<version>-bin-hadoop<hadoop-version>.tar.gz

移动到 /usr/lib/sqoop 目录

1
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

1
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：

1
2
3
4
5
6
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：

1
2
3
4
5
6
7
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

1
sudo vim /usr/lib/sqoop/conf/sqoop.properties

找到 org.apache.sqoop.submission.engine.mapreduce.configuration.directory 参数，如下：

1
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：

1
org.apache.sqoop.submission.engine.mapreduce.configuration.directory=/usr/hdp/3.1.0.0-78/hadoop/conf/

导入第三方 jar 包

1
2
3
4
5
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

1
sudo vim ~/.bashrc

添加环境变量，如下：

1
2
3
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：

1
source ~/.bashrc

修改 Ambari 上组件配置

修改组件 HDFS 配置

配置项 参数名 初始值 修改值
Advanced hdfs-site dfs.permissions.enabled True False
Custom core-site hadoop.proxyuser.hive.hosts *
Custom core-site hadoop.proxyuser.root.hosts *
Custom core-site hadoop.proxyuser.sqoop2.groups *
Custom core-site hadoop.proxyuser.sqoop2.hosts *
Custom core-site hadoop.proxyuser.yarn.groups *
Custom core-site hadoop.proxyuser.yarn.hosts *

修改组件 MapRduce2 配置

将 ${hdp.version} 替换成实际 hdp 的版本: 3.1.0.0-78

配置项 参数名 初始值 修改值
