Subject Re: HDFS Installation
Date Sun, 13 Apr 2014 17:36:53 GMT
Hi,

I started with "ssh localhost" command.
Does anything else is needed to check SSH?

Then I stopped all the services which were running by "stop-all.sh"
and start them again with "start-all.sh".

I have copied the way it executed on the terminal for some commands.

I don't know, why after start-all.sh it says starting namenode and does not
show any failure but
when I check through jps it does not list namenode.

I tried opening namenode in browser. It is also not getting open.

----------------------------------------------------------------------------------------------------------------------------------------

These is the way it executed on terminal:

hduser@ubuntu:~$ ssh localhost
hduser@localhost's password:
