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.

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.
