一异常原因用Sqoop将数据从mysql导入到Hbase表出现异常如下：

[root@master bin]# ./sqoop import --connect jdbc:mysql://192.168.10.169/qyyx_test --username root --

password sendinfo --table spread_log --hbase-create-table --hbase-table phone --column-family info

二异常原因

上面异常由由于mysql-connector-java-5.1.6/中mysql-connector-java-5.1.10-bin.jar放到sqoop-1.4.6.bin__hadoop-2.0.4-alpha/lib下版本出现问题。

三解决方案

将mysql-connector-java-5.1.10-bin.jar换成mysql-connector-java-5.1.39-bin.jar
