Question

在Ubuntu上，使用couchbase 2.5.1，cloudera cdh4，couchbase和oracle jdk的hadoop插件6.一切安装都很好（貌似），我可以独立使用hadoop和couchbase没有任何问题，但是当我尝试使用插件如下

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？或者我能做些什么才能找到答案？

Answer 1

似乎我使用的语法错了。假设我们要将beer-sample存储桶从couchbase导入HDFS，下面是正确的语法，其中存储桶名称实际上是username传递的。

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

Answer 2

我不认为您可以使用couchbase hadoop插件连接到带密码的couchbase存储桶。我曾经获得身份验证异常，但从未能解决它。我编辑了源代码，然后我就能使它工作。

Sqoop从couchbase导入到hadoop
