Mysql 在HDFS-beugs中使用sqoop导入数据

我遵循这个教程。我已经使用cloudera manager安装了hadoop服务（hdfs、hive、sqoop、hue等等）。 我正在使用Ubuntu12.04TLS。 当尝试将数据从Mysql导入HDFS时，mapreduce作业会花费无限的时间而不会返回任何错误。知道导入的表有4列10行

我就是这么做的：

    sqoop import --connect jdbc:mysql://localhost/employees --username hadoop --password password --table departments -m 1 --target-dir /user/sqoop2/sqoop-mysql/department

请注意，

MapReduce作业未启动。您需要在集群上运行测试wordcount作业。

您发布的日志有一个部分

用于跟踪作业的url:

您可以在下次运行作业时查找url以检查Map Reduce日志。看起来您的连接正在以
