Doing the following:
From tMap to tHDFSoutput
CDH 5.5
this is my name node urI "hdfs://ipaddress:8020"
user name 'cloudera'
file type text
action append
file name "/user/dor/dor.txt"

Where am i wrong ?

Is your name node uri literally "hdfs://ipaddress:8020", or is ip address replacing and actual ip address?
I am assuming that your name node machine is not called "ipaddress".

Of course, the ip is the one cloudera runs over, in my case 10.0.0.8 - wrote ipaddress to save all this explanation.

Just thought I would ask. You'd be surprised what some people ask on here. If you were to look at some of the problems, you would think that companies are letting work experience kids run their DI/ESB/BigData systems.
