解决：Sqoop导入数据到Hive连接hiveserver2卡住

问题

• 执行sqoop job要将mysql中数据导入hive表，执行到连接hiveserver2时就卡住不动
• 单独执行连接hiveserver2可以正常连接

Import options:

sqoop import --connect jdbc:mysql://xxx:3306/test --username xxxxx --password xxxxxx 
--table t_user 
--fields-terminated-by '\001' 
--hive-import 
--hive-database sqoop2hive
--hive-table t_user_hive 
--hive-overwrite 
--delete-target-dir --m 1

Output:

就停在这：

连接不上 hiveserver2。

解决

在hive conf目录（一般在/etc/hive/conf）新建（如果没有）一个beeline-hs2-connection.xml文件：

 beeline.hs2.connection.user
 hive


 beeline.hs2.connection.password
 hive

熄灯
