我正在尝试将数据从mysql表导入hdfs。我正在使用下面的sqoop导入命令

sqoop import --connect jdbc:mysql://localhost:3306/employee --username root --password***--table Emp --m 1

我得到下面的错误

16/05/07 20:01:18 ERROR tool.ImportTool: Encountered IOException running import job: java.io.FileNotFoundException: File does not exist: hdfs://localhost:54310/usr/lib/sqoop/lib/parquet-format-2.0.0.jar

我在usr/lib/sqoop文件夹中有parquet-format-2.0.0.jar，但即使这样它也显示了错误。
我试图将所有的sqoop库导入hdfs，但是我可以做到这一点：抛出下面的错误

你现在能做什么？我不能将jar文件复制到hdfs，也不能将数据从mysql导入hdfs。
我尝试了此解决方案sqoop import eror-文件不存在：
但不能从第二步开始。我还清除了缓存并重新启动了hadoop文件系统。
谢谢
