Java 使用ApacheSqoop从MySQL导入数据-错误：没有用于连接字符串的管理器

我正在尝试将Mahout与外部数据源集成。为此，我在照本宣科

我已经配置了Hadoop2.4、MySQL服务器，并将一个虚拟数据库导入MySQL

我还按照书中的步骤安装了ApacheSqoop，并在Sqoop库（Sqoop/lib）中下载和部署了mysql-connector-java-5.1.30.jar

我使用ant命令构建了sqoop：

   ant mvn-install

建造得很好

我正试图使用书中描述的以下命令从mysql导入数据：

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

但它失败了，出现了以下错误：

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.

有人能帮我找到我丢失的东西吗？为什么会产生此错误？我如何解决它

PS:我没有安装HBase或HCatalog，因为书上说我不需要它。

看起来你的jdbc url不正确，应该是这样的

jdbc:mysql://localhost/bbdatabank

我也尝试过jdbc：mysql://localhost:3306:bbdatabank/ 正在设置端口，但效果不太好。您是收到相同的异常还是更改了异常？。顺便提一下端口号为的URL为。jdbc：mysql://localhost:3306/bbdatabank/I 您也尝试过jdbc：mysql://localhost:3306:bbdatabank/ 正在设置端口，但效果不太好。您是收到相同的异常还是更改了异常？。顺便提一下端口号为的URL为。jdbc：mysql://localhost:3306/bbdatabank/
