从Couchbase导入Sqoop导入到Hadoop

Question

在Ubuntu上，使用Couchbase 2.5.1，Cloudera CDH4，Couchbase和Oracle JDK 6.一切都安装精细（似乎），我可以独立地与Hadoop和Couchbase一起使用，没有任何问题，但是当我尝试使用时插件如下

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

.

我收到以下错误

我出错的想法吗？或者我能做些什么来发现？

Answer 1

似乎我使用的语法错了。假设我们希望将来自Couchbase导入的beer-sample存储桶到HDFS中，正确的语法如下所示，其中桶名称实际上作为username。

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

.

Answer 2

我不认为您将能够使用Couchbase Hadoop插件与密码连接到Couchbase桶。我曾经获得身份验证异常，并且从未能解决它。我编辑了源代码，然后我能够完成它。
