Hadoop command not found

I got the same error, and this worked for me

I configured path variable in.bashrc.

export HADOOP_HOME=/opt/hadoop

export PATH= $PATH:$HADOOP_HOME/bin

Sometime restarting your machine can resolve the issue ,only if you have configured everything correct.

edit PATH variable, if you want to be able to invoke hadoop without specifying full path

export PATH=$PATH:/usr/local/hadoop/bin/

if you want it for each bash profile then edit ~/.bash_profile to include this

cd ~

vi .bashrc

export PATH=$PATH:<hadoop installation path>

for example replace <hadoop installation path> by /usr/local/hadoop/bin/

As it seems from your commands history, you can replace hadoop by /usr/local/hadoop/bin/hadoop and it should help.

If you want to use hadoop command without specifying the full path to it, you can edit ~/.bashrc file and add the following line:

export PATH=$PATH:/usr/local/hadoop/bin/

Then you need to reopen your terminal.
