sqoop 将数据导入hive注意事项

---

1.在sqoop的配置文件 sqoop-env.sh配置如下

export HADOOP_COMMON_HOME=/soft/hadoop
export HADOOP_MAPRED_HOME=/soft/hadoop
export HIVE_HOME=/soft/hive

2.将hive安装目录下的的lib目录下的jar包导入到sqoop安装目录lib下

cp /soft/hive/lib/hive-common-1.2.2.jar /soft/sqoop/lib/
cp /soft/hive/lib/hive-exec-1.2.2.jar /soft/sqoop/lib/
