HI Mohammed,

There is space between -ls and /

"hadoop fs -ls /"

is the command.

Thanks,
Sharon

I followed the space between them while using terminal windows version 64 bit.

I was able to practice Hadoop commands using your AWS connecting through PUTTY, so I am familiar with those commands.

hi Mohammad,

Please confirm if the issue is addressed.

Thanks

It is not fixed yet. I went to C:/windows/system32/drivers/etc/host and remove # from 127.0.0.1 but I get different error message. In my other computer I get same message while running final script on wordcount.

Does anyone know how to follow these instruction to resolve about issue:

I had similar issues - Actually Hadoop was binding to IPv6. Then I Added - "export HADOOP_OPTS=-Djava.net.preferIPv4Stack=true " to $HADOOP_HOME/conf/hadoop-env.sh

Hadoop was binding to IPv6 even when I had disabled IPv6 on my system. Once I added it to env, started working fine.
