Question

我试图将Mahout与外部数据源集成。我正在关注Apache Mahout Cookbook本书。

我已经配置了Hadoop 2.4，MySQL服务器，我已经将一个虚拟数据库导入mysql。

我按照本书中的步骤安装了Apache Sqoop，并在Sqoop库中下载并部署了mysql-connector-java-5.1.30.jar（sqoop / lib）

我用ant命令构建了sqoop：

   ant mvn-install

构建顺利。

我尝试使用以下命令从mysql导入数据，如本书所述：

   sqoop import-all-tables --connect jdbc:mysql/localohost/bbdatabank --username root -P --verbose

但它没有跟随错误：

Warning: /usr/lib/hbase does not exist! HBase imports will fail.
Please set $HBASE_HOME to the root of your HBase installation.
Warning: /usr/lib/hcatalog does not exist! HCatalog jobs will fail.
Please set $HCAT_HOME to the root of your HCatalog installation.

有人可以帮我找到我失踪的东西吗？为什么会产生此错误？如何解决？

PS：我还没有安装HBase，也没有安装HCatalog因为这本书说我不需要它。

看起来您的jdbc网址不正确，应该是

jdbc:mysql://localhost/bbdatabank

使用Apache Sqoop从MySQL导入数据 - 错误：没有连接字符串管理器
