RE : Re: problems with start-all command

[kawther khazri <nu...@yahoo.fr>]

thank you verry mutch for your help.

Dennis Kubes <nu...@dragonflymc.com> a écrit :  The name node is running. Run the bin/stop-all.sh script first and then 
do a ps -ef | grep NameNode to see if the process is still running. If 
it is, it may need to be killed by hand kill -9 processid.
The second problem is the setup of ssh keys as described in previous 
email. Also I would recommend NOT running the namenode as root but in 
having a specific user setup to run the various servers as described in 
the tutorial.

> what is the différence between the two. what's the meaning this message:"namenode running as process 16323. Stop it first." Is it normal to obtain this. I don't know the cause of this error.
