我正在尝试使用hadoop中的sqoop从mysql的employee数据库导入employee表。我使用的是hadoop版本“2.7.1”，sqoop版本“1.4.6”，jdk版本“1.8.0\u111”，mysql版本是“5.7.17”。我已经启动了所有的hadoop服务。但当我试图从mysql数据库导入表时，我遇到了一个异常。
我已经尝试过sqoop中提到的方法，但无法导入表来解决我的问题，但它们都不适合我。
sqoop的安装路径是： /usr/local/sqoop/ 我用来导入数据的命令是：

bin/sqoop import --connect jdbc:mysql://localhost:3306/Employee --table employee --username root --password root --m 1 --target-dir /user/sqoop/sqlimport/employee

我得到的例外是：

Warning: /usr/local/sqoop/bin/../../hbase does not exist! HBase imports will fail.
Please set $HBASE_HOME to the root of your HBase installation.
Warning: /usr/local/sqoop/bin/../../hcatalog does not exist! HCatalog jobs will fail.

在这个问题上花了许多小时后，我自己找到了解决办法。我需要使用 --bindir 选项指向sqoop的安装目录，通知sqoop服务从何处选择jar文件。
我将数据从mysql导入hdfs的命令是：

bin/sqoop import --connect jdbc:mysql://localhost:3306/Employee --username root --password root --m 1  --table employee --bindir /usr/local/sqoop/ --target-dir /user/sqoop/sqlimport/employee

我将数据从hdfs导出到mysql的命令是：

bin/sqoop export --connect jdbc:mysql://localhost:3306/Employee --username root --password root --m 1 --table employeeexported --bindir /usr/local/sqoop/ --export-dir /user/sqoop/sqlimport/employee/part-m-00000
