Hello,

As far as I know, 'client' in this context is referring the program or the
entity who tries to interact with the HDFS. For example, if I try

bin/hadoop dfs -put /proj/input myinput  
//this brings the folder /proj/input locally to myinput on HDFS

I am the client in this case. (or the node that I am currently using to
submit)

Hope this helps.

Best Regards

Subject: some questions about client in hadoop

Hello,

In the file hdfs_design.pdf,it tells us that "A client-request to create a
file does not reach the Namenode immediately...",so I just want to ask that
what does "client" exactly mean,and how to set up a client in the HDFS?

I have tried the command:
[EMAIL PROTECTED]:hadoop]$bin/hadoop dfs -fs local|dbrg-1:9000
but it didn't work!

Please help me.
Thanks a lot.
