Question

我从几天开始学习sqoop并成功安装并配置了hadoop。

hadoop_usr@sawai-Lenovo-G580:/usr/local/sqoop/bin$ sqoop2-server start
Setting conf dir: /usr/local/sqoop/bin/conf
Sqoop home directory: /usr/local/sqoop
The Sqoop server is already started.
hadoop_usr@sawai-Lenovo-G580:/usr/local/sqoop/bin$ sqoop
sqoop: command not found

sqoop服务器已在运行，当我尝试触发sqoop命令时，我收到错误消息。 command not found。 sqoop home已经在路径

export HADOOP_HDFS_HOME=$HADOOP_HOME
export YARN_HOME=$HADOOP_HOME
export HADOOP_COMMON_LIB_NATIVE_DIR=$HADOOP_HOME/lib/native
export PATH=$PATH:$HADOOP_HOME/sbin:$HADOOP_HOME/bin
export HADOOP_INSTALL=$HADOOP_HOME

export SQOOP_HOME=/usr/local/sqoop
export SQOOP_CONF_DIR=$SQOOP_HOME/conf
export SQOOP_CLASSPATH=$SQOOP_HOME/server/lib
export PATH=$PATH:$SQOOP_HOME/bin:$SQOOP_CONF:$SQOOP_CLASSPATH

$ echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/usr/local/hadoop/sbin:/usr/local/hadoop/bin:/usr/local/sqoop/bin::/usr/local/sqoop/server/lib

请帮我解决此问题。

提前致谢。

Answer 1

大多数情况下发生

command not found错误是因为路径没有设置相同。

请设置您已经完成的sqoop路径。 export PATH = $ PATH：$ SQOOP_HOME / bin：$ SQOOP_CONF：$ SQOOP_CLASSPATH

编译已设置 $ PATH 的文件或重新启动终端。

Answer 2

将以下命令放在.bashrc文件中

export SQOOP_HOME=/home/pj/sqoop 
export PATH=$PATH:$SQOOP_HOME/bin

并重新启动.bashrc

source .bashrc

如果问题仍然存在，请重启终端。

sqoop已启动，但未找到命令show sqoop命令
