Hadoop command not found

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.

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

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.

cd ~

vi .bashrc

export PATH=$PATH:<hadoop installation path>

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