【中文标题】SQOOP 服务器已启动但未找到错误命令

【英文标题】：SQOOP Server started but getting an error command not found

【发布时间】：2018-02-23 11:12:31

【问题描述】：

我使用的是 ubuntu 16.04 版

harsha@ubuntu:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 16.04.3 LTS
Release:    16.04
Codename:   xenial

我能够启动 sqoop 服务器和 sqoop shell，但是当我在终端中输入 sqoop help 或 sqoop import 时，它说找不到命令。

错误是

harsha@ubuntu:~$ sqoop help
sqoop: command not found
harsha@ubuntu:~$ sqoop -help
sqoop: command not found
harsha@ubuntu:~$ sqoop --help
sqoop: command not found
harsha@ubuntu:~$ sqoop
sqoop: command not found

下面的命令工作得很好。

sqoop2-tool upgrade
sqoop2-tool verify
sqoop2-server start
sqoop2-server stop
sqoop2-shell

这里是回声 $PATH

/home/harsha/bin:/home/harsha/.local/bin:/usr/local/sbin:/usr/local/bin:
/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:
/usr/lib/jvm/java-8-oracle/bin:/opt/hadoop-3.0.0/bin:

/opt/zookeeper-3.5.3-beta/bin:/usr/lib/sqoop-1.99.7-bin-hadoop200/bin:/usr/lib/sqoop-1.99.7-bin-hadoop200/conf:

当前正在运行的进程是

harsha@ubuntu:~$ jps

~/.bashrc 文件中的条目如下

            export JAVA_HOME=/usr/lib/jvm/java-8-oracle

如果有人可以帮助我，那将是一个很大的帮助。感谢您的帮助。

我现在卡住了，任何建议都将不胜感激

【参考方案1】：

找到 sqoop 命令并将命令的路径添加到 $PATH 变量中。

locate sqoop
