SQOOP无法导入表格

我正在sqoop上运行命令

sqoop import --connect jdbc:mysql://localhost/hadoopguide --table widgets

我的sqoop版本:Sqoop 1.4.4.2.0.6.1-101
Hadoop - Hadoop 2.2.0.2.0.6.0-101

两者均取自hortonworks分销.HADOOP_HOME,HCAT_HOME,SQOOP_HOME等所有路径都已正确设置.我可以通过在sqoop中运行list-database,list-tables命令从mysql数据库获取数据库列表,表列表.甚至能够从--query'select*from widgets'获取数据; 但是当我使用--table选项低于错误.

指定--bindir编译的代码和.jar文件的位置.

如果没有这些参数,Sqoop会将生成的Java源文件放在当前工作目录中,并将编译后的.class文件和.jar文件放入/tmp/sqoop-/compile.
