在 Ubuntu 上，使用 couchbase 2.5.1、cloudera cdh4、用于 couchbase 和 oracle jdk 6 的 hadoop 插件。一切都安装得很好（似乎），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

我收到以下错误

知道我哪里出错了吗？或者我能做些什么来找出答案？

我认为您无法使用 couchbase hadoop 插件连接到带有密码的 couchbase 存储桶。我曾经获得身份验证异常并且永远无法解决它。我编辑了源代码，然后我就可以让它工作了。

看来我使用的语法是错误的。假设我们要将beer-sample存储桶从 couchbase 导入 HDFS，正确的语法如下，其中存储桶名称实际上是作为username.

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