我从Cloudera tarball安装了sqoop2。 我能够安装sqoop2服务器和客户端。
安装后，"http://localhost:12000"地址会显示结果
包含字符串“Apache Sqoop ROOT”。我从这个字符串中理解
服务器正在运行，但是当我请求时
"http://localhost:12000/sqoop/version"它给出了：
HTTP状态404
当我这样做时，在客户端shell中 显示版本-all
我收到此消息
处理命令期间发生异常
例外：com.sun.jersey.api.client.UniformInterfaceException消息：GET http://172.20.104.226:12000/sqoop/version返回的响应状态为404 Not Found

答案 0 :(得分：0)
我认为根本例外就是这个：
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。您已经提到您已经通过tarbals而不是软件包安装了Sqoop，因此您需要更改catalina.properties文件。我建议查看default example file并使用Hadoop依赖项的适当位置更改配置文件。
答案 1 :(得分：0)
我认为您需要确保在sqoop.properties内部，应将hadoop配置目录org.apache.sqoop.submission.engine.mapreduce.configuration.directory设置为存在hadoop配置文件的正确目录。它默认设置为/etc/hadoop/conf，但就我而言，它实际上位于/root/hadoop-2.7.3/etc/hadoop下
答案 2 :(得分：0)
请考虑这些要点来跟踪sqoop2问题。
确保您的hadoop namenode 群集正在运行无密钥（即没有密码）。
确保 NameNode，DataNode，NodeManager，ResourceManager，SecondaryNameNode＆amp; JobHistoryServer 正在您的系统上运行。
使用编辑你的“ catalina.properties ”文件，其中包含加载hadoop库的绝对路径，因为有时相对路径无法正常工作。在我的情况下。
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/common/*.jar,/home/infinity/HADOOP/hadoop/share/hadoop/common/lib/*.jar,/home/infinity/HADOOP/hadoop/share/hadoop/hdfs/*.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/infinity/HADOOP/hive/lib/*.jar
使用 @BASEDIR @ 上的绝对路径**和 sqoop.properties 文件中的 @LOGDIR @ ，以便轻松跟踪sqoop日志文件。
确保sqoop.properties文件中的hadoop实例目录位置可用。就我而言，这些都是。
org.apache.sqoop.submission.engine=org.apache.sqoop.submission.mapreduce.MapreduceSubmissionEngine
org.apache.sqoop.submission.engine.mapreduce.configuration.directory=/home/infinity/HADOOP/hadoop/etc/hadoop
org.apache.sqoop.execution.engine=org.apache.sqoop.execution.mapreduce.MapreduceExecutionEngine
如果所有设置都正常，则使用启动 sqoop2-server sqoop.sh服务器启动
注意： - 1.但是，在运行此命令之前，使用此命令 Hadoop namenode -format 格式化您的hadoop群集名称节点，然后启动 sqoop2-server 。
如果这些设置在您的系统中完全正常，那么这不是配置问题。 它可能是一个jar兼容性问题。因为它仅在缺少本机jar文件或当前环境不支持第三方jar文件时发生。我建议你请确保“catalina.properties”具有所有基本的本机依赖jar文件。
