我从Cloudera安装了sqoop2。我能够安装sqoop2服务器和客户端。

安装后，"http://localhost:12000"地址将给出包含字符串"Apache“的结果。我从这个字符串中了解到服务器正在运行，但是当我请求"http://localhost:12000/sqoop/version"时，它会给出：

HTTP状态404

在客户端shell中，当我显示版本-all时

我收到这条消息

异常在处理命令异常期间发生: com.sun.jersey.api.client.UniformInterfaceException消息: GET http://172.20.104.226:12000/sqoop/version返回响应状态404未找到

我认为，根本的例外是：

Caused by: java.lang.ClassNotFoundException: org.apache.hadoop.mapred.JobClient

似乎Sqoop服务器无法找到它的Hadoop依赖项。您已经提到通过tarbals而不是包安装了Sqoop，因此需要修改catalina.properties文件。我建议查看一下默认示例文件，并使用Hadoop依赖项的适当位置修改配置文件。

我认为您需要确保在sqoop.properties中，org.apache.sqoop.submission.engine.mapreduce.configuration.directory配置目录应该设置为存在hadoop配置文件的正确目录。默认情况下，它设置为/etc/hadoop/conf，但在我的示例中，它实际上位于/root/hadoop-2.7.3/etc/hadoop下面。

请考虑以下几点来跟踪sqoop2问题。

  1. 确保您的hadoop namenode集群正在运行无密钥(即没有密码)。
  2. 确保NameNode、DataNode、NodeManager、ResourceManager、SecondaryNameNode & JobHistoryServer在您的系统上运行。
  3. 使用带有绝对路径的编辑"catalina.properties“文件来加载hadoop库，因为有时相对路径不起作用，properly.in是我的情况。 /home/infinity/HADOOP/hadoop/share/hadoop/common/*.jar，/home/infinity/HADOOP/hadoop/share/hadoop/common/lib/*.jar，/home/infinity/HADOOP/hadoop/share/hadoop/hdfs/*.jar，common.loader=${catalina.base}/lib，${catalina.base}/lib/*..jar，${catalina.home}/lib，${catalina.home}/lib/*..jar，${catalina.home}/../lib/*..jar/home/infinity/HADOOP/hadoop/share/hadoop/hdfs/lib/*.jar，/home/infinity/HADOOP/hadoop/share/hadoop/mapreduce/*.jar，/home/infinity/HADOOP/hadoop/share/hadoop/mapreduce/lib/*.jar，/home/infinity/HADOOP/hadoop/share/hadoop/yarn/*.jar，/home/infinity/HADOOP/hadoop/share/hadoop/yarn/lib/*.jar，/home/infinity/HADOOP/hadoop/share/hadoop/tools/lib/*.jar，/home/无穷/HADOOP/hive/lib/*..jar
  4. 使用sqoop.properties文件中的@BASEDIR@和@LOGDIR@位置上的绝对路径**，以便轻松跟踪sqoop日志文件。
  5. 确保sqoop.properties文件中有hadoop实例目录位置。就我而言，这些是。 提交引擎类 org.apache.sqoop.submission.engine=org.apache.sqoop.submission.mapreduce.MapreduceSubmissionEngine Hadoop配置目录 org.apache.sqoop.submission.engine.mapreduce.configuration.directory=/home/infinity/HADOOP/hadoop/etc/hadoop 执行引擎配置 org.apache.sqoop.execution.engine=org.apache.sqoop.execution.mapreduce.MapreduceExecutionEngine
  6. 如果所有设置都很好，那么使用sqoop.sh服务器启动

注意：- 1.但是，在运行此命令格式之前，使用以下命令运行hadoop集群namenode，然后启动sqoop2-server.

如果这些所有设置在您的系统中都是非常好的，那么这不是一个配置问题。这可能是一个jar兼容性问题。因为只有在本机jar文件丢失或当前环境不支持第三方jar文件时才会发生这种情况。我建议您确保"catalina.properties“拥有所有基本的本机依赖jar文件。
