sqoop import 报错Communications link failure
1.问题描述
sqoop list-tables 工具正常，但是import 工具有问题。奇怪！！！！
[hadoop@master ~]$ sqoop import --username test --password test --connect jdbc:mysql://172.1.1.96:3306/test -m 1 --delete-target-dir --table student_exam_score_20170802 --fields-terminated-by '\t' --hive-import --hive-database bond_edu --hive-table student_exam_score_20170802

[hadoop@master ~]$ 2.问题解决
2.1 mysql 在本地（sqoop本地）
这个查询资料：
1. 把url localhost 改成ip(配置/etc/hosts 文件即可)
sqoop import --username test --password test --connect jdbc:mysql://127.0.0.1:3306/test?autoReconnect=true --delete-target-dir --table t --fields-terminated-by '\t' -m 1 --hive-import --hive-database test --hive-table t
2.给用户赋权（如果有权限，忽略）
grant all privileges on test to test@'%' IDENTIFIED BY 'test' WITH GRANT OPTION;
flush PRIVILEGES;locahost导入失败：
[hadoop@master ~]$ sqoop import --username test --password test --connect jdbc:mysql://127.0.0.1:3306/test?autoReconnect=true --delete-target-dir --table t --fields-terminated-by '\t' -m 1 --hive-import --hive-database test --hive-table t

2.2 mysql 不在本地（远程）
hadoop 是集群（多个节点），多数据节点，务必保证N个数据节点都能访问mysql 数据库（N 取决于sqoop 指定的 -m参数后的 N，大于等于-m 后面的参数），sqoop 底层运行的MR，MR运行在hadoop 集群上，所以hadoop 每个节点都必须能连接mysql 数据库，可用mysql -h***** -u***** -p***** 测试。
我的环境：
三台虚拟机，每个两块网卡，一块私有（集群间通讯），一块公用桥接（与外面机器通讯）
| 节点 | IP |
| master | 10.0.1.118 |
| slave-1 | 10.0.1.227 |
| slave-2 | 10.0.1.226 |
slave-1 连接远程数据库:
slave-2 连接远程数据库：

[hadoop@master ~]$ 总结：
1.sqoop 远程导入mysql数据到hive 必须保证N个数据节点能正常连接改远程数据库（N 大于等于sqoop 并行数）。
2.sqoop 本地导入 用户可能需要用IP或者修改host文件。
3.sqoop list-tables 不需要数据节点？（存疑？？）。
