我正在尝试使用Sqoop版本1.4.6.2.6.5.0-292将数据从HyperSQL数据库表导入Hadoop DFS。我将尝试总结我已采取的步骤：
首先，我下载并解压缩了HSQL 1.8.0.10版本（与Sqoop中使用的版本相同）。我添加了一个server.properties文件，并像这样配置数据库文件夹：server.database.0=file:test/test
数据库服务如下启动：
nohup java -cp /data/programs/ETU/hsqldb-1.8.0/hsqldb/lib/hsqldb.jar org.hsqldb.Server＆
sqoop list-tables --connect "jdbc:hsqldb:hsql://localhost" --connection-manager "org.apache.sqoop.manager.HsqldbManager" --username "SA"断言来自sqoop的成功连接结果显示了我希望的一张表RT_SALES。但是，当尝试使用
实际将数据导入HDFS时sqoop import --num-mappers 1 --connect "jdbc:hsqldb:hsql://localhost" --connection-manager "org.apache.sqoop.manager.HsqldbManager" --username "SA" --table "RT_SALES" --target-dir "/some-folder"
我收到以下错误：

从其他帖子来看，该消息表明HSQLDB没有运行。但是，我能够使用集成的HSQL客户端进行连接，并且如上所述，sqoop至少可以查询表-因此该服务必须正在运行。
我已经尝试过（没有成功）：
