ERROR hive.HiveConfig: Could not load org.apache.hadoop.hive.conf.HiveConf. Make sure HIVE_CONF_DIR is set correctly.

Sqoop导入mysql表中的数据到hive，出现如下错误： 

 ERROR hive.HiveConfig: Could not load org.apache.hadoop.hive.conf.HiveConf. Make sure HIVE_CONF_DIR is set correctly.

命令如下：

./sqoop import --connect jdbc:mysql://slave2:3306/mysql --username root --password aaa --table people --hive-import --hive-overwrite --hive-table people --fields-terminated-by ' ';

 解决方法：

往/etc/profile最后加入 export HADOOP_CLASSPATH=$HADOOP_CLASSPATH:$HIVE_HOME/lib/*
然后刷新配置，source /etc/profile
