Apache Sqoop 数据转换安装配置与基本操作命令

系统环境

CentOS 6.5

组件版本

name version
Sqoop 1.4.6

Sqoop 安装

解压

懒的敲了

  • 配置环境变量
# SQOOP
SQOOP_HOME=/home/Hadoop/development/src/sqoop-1.4.6-cdh5.6.0
PATH=$PATH:$SQOOP_HOME/bin
export PATH

cd 到 Sqoop 根目录

配置 Sqoop 核心文件

主要配置 ${SQOOP_HOME}/conf/sqoop-env-template.sh 文件

cp ${SQOOP_HOME}/conf/sqoop-env-template.sh ${SQOOP_HOME}/conf/sqoop-env.sh

主要修改参数

# 指定 Hadoop 安装目录
export HADOOP_COMMON_HOME=
# 指定 Hadoop MapReduce 技术 jar 存放目录
export HADOOP_MAPRED_HOME=
# Hbase 安装目录
export HBASE_HOME=
# Zookeeper 安装目录
export ZOOCFGDIR=

如果没有安装的可以不用填写

例如

#Set path to where bin/hadoop is available
export HADOOP_COMMON_HOME=/home/hadoop/development/src/hadoop-2.6.0-cdh5.6.0

#Set path to where hadoop-*-core.jar is available
"这里之所以和 Hadoop 安装目录一样,是由于上次我配置成 mapreduce jar 地址时,sqoop 报错"
export HADOOP_MAPRED_HOME=/home/hadoop/development/src/hadoop-2.6.0-cdh5.6.0

#set the path to where bin/hbase is available
"我没有安装 Hbase 所以这里直接 注释掉就可以"
#export HBASE_HOME=

#Set the path to where bin/hive is available
export HIVE_HOME=/home/hadoop/development/src/hive-1.1.0-cdh5.6.0

#Set the path for where zookeper config dir is
export ZOOCFGDIR=/home/hadoop/development/src/zookeeper-3.4.5-cdh5.6.0

注释掉没有使用的组件

bin/config-sqoop

#if [! -d "${HBASE_HOME}" ]; then
#  echo "Warning: $HBASE_HOME does not exist! HBase imports will fail."
#  echo 'Please set $HBASE_HOME to the root of your HBase installation.'
#fi

# Moved to be a runtime check in sqoop.
#if [! -d "${HCAT_HOME}" ]; then
#  echo "Warning: $HCAT_HOME does not exist! HCatalog jobs will fail."
#  echo 'Please set $HCAT_HOME to the root of your HCatalog installation.'
#fi

#if [! -d "${ACCUMULO_HOME}" ]; then
#  echo "Warning: $ACCUMULO_HOME does not exist! Accumulo imports will fail."
#  echo 'Please set $ACCUMULO_HOME to the root of your Accumulo installation.'
#fi
#if [! -d "${ZOOKEEPER_HOME}" ]; then
#  echo "Warning: $ZOOKEEPER_HOME does not exist! Accumulo imports will fail."
#  echo 'Please set $ZOOKEEPER_HOME to the root of your Zookeeper installation.'
#fi

Sqoop 操作笔记

mysql 导出到 HDFS

import 导入

–connect‘jdbc:mysql://192.168.2.251:3306/canbot?characterEncoding=UTF-8’链接数据库语句

–username root –password root 账号密码

–table kylin01 指定 mysql 中 canbot 库中的 kylin01 表

–target-dir‘/yuqi_dir/sqoop/kylin01’指定将表到导入到 HDFS 中的路径

-m 1 运行 map 数量

./bin/sqoop import --connect 'jdbc:mysql://192.168.2.251:3306/canbot?characterEncoding=UTF-8' --username root --password root --table kylin01 --target-dir '/yuqi_dir/sqoop/kylin01' -m 1 

查看 kylin01 表数据

--table a # 指定导入到那张表
--export-dir /yuqi_dir/sqoop/kylin01/part-m-00000 # 要导入的文件存在 HDFS 的路径
-m 2 # 运行 map 的个数

Mysql 直接导入到 Hive

sqoop import --connect 'jdbc:mysql://192.168.2.251:3306/canbot?characterEncoding=UTF-8' --username root --password root 
--table a # 标记要导出的 mysql 表
