Question

我在两个节点集群上使用Hadoop-2.2.0，hadoop配置正确且工作正常，现在我正在尝试安装sqoop 2（sqoop-1.99.3-bin-hadoop200）并尝试访问sqoop 2 web UI（如localhost：12000）得到以下内容。

Apache Sqoop ROOT

当尝试访问cloudera.com:12000/sqoop/version时，我会得到关注 HTTP状态404 - 当我在sqoop客户端中使用它时

[stratapps@cloudera2 ~]$ sqoop.sh client
Sqoop home directory: /usr/local/sqoop2
Sqoop Shell: Type 'help' or '\h' for help.



sqoop:000> set server --host cloudera.com --port 12000 --webapp sqoop
Server is set successfully
sqoop:000> show version --all
client version:
  Sqoop 1.99.3 revision 2404393160301df16a94716a3034e31b03e27b0b

我的common.loader的catelina.proparties文件看起来像

common.loader=
${catalina.base}/lib,
${catalina.base}/lib/*.jar,

我的Sqoop.proprties文件org.apache.sqoop.submission.engine.mapreduce.configuration.director y看起来像

# Hadoop configuration directory
org.apache.sqoop.submission.engine.mapreduce.configuration.directory=/usr/local/hadoop/hadoop-2.2.0/etc/hadoop

请分享您的意见我对此有很多关注，但是找不到任何解决方案。

为什么要将sqoop服务器的主机名设置为cloudera.com？使用机器的主机地址，其中sqoop服务器正在运行。如果您使用的是单台计算机，请将cloudera.com更改为localhost。

在Sqoop2客户端API中提交作业时出现问题
