I tried installing hadoop and I no longer need stuff from it. When launching shell , it gives the following and many commands are unrecognized now , how do I reset it to default ?
bash: export:
`/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:
/bin:/usr/games:/usr/local/games:/usr/local/hadoop/bin': not a valid
