从couchbase到hadoop的Sqoop导入

在Ubuntu上，使用couchbase 2.5.1、cloudera cdh4、couchbase的hadoop插件和oracle jdk 6。一切都安装得很好（看起来），我可以独立使用hadoop和couchbase，没有问题，但是当我尝试使用插件时，如下所示

sqoop import --connect http://127.0.0.1:8091/ --table DUMP

我得到以下错误

知道我哪里出错了吗？或者我能做些什么来找出答案？

我使用的语法似乎是错误的。假设我们想要将

啤酒样本

桶从couchbase导入HDFS，下面是正确的语法，其中桶名实际上作为

用户名

传递

sqoop import --connect http://localhost:8091/pools --password password --username beer-sample --table DUMP

我不认为你能用couchbase hadoop插件用密码连接到couchbase bucket。我曾经遇到过身份验证异常，但始终无法解决它。我编辑了源代码，然后我就可以让它工作了
