Problem with HDFS

[_AnonymousUser]

Hello,
First of all, I want to apologize for my English that is not really good.
Let me explain my problem. It comes from HDFS. Indeed, my objective is to send a file to a HDFS cluster. Then I've ask for all the informations to the administrator, who has given then to me. But, when I try to send/read any data from/to the HDF System, I ALWAYS got this exasperating error as response:

Exception in component tHDFSExist_1

Does anyone have any idea of the origin of the problem: does it come from TOS, or otherwise is it me who made an error in the configuration?

Is this issue is fixed. We are facing a similar kind of issue.
I have talend tool installed in windows environment and tried to build hdfsconnection. But not able to successfully connect tried with different  element(thdfsget/thdfsput/thdfsinput/thdfsoutput) but no success.
Tried with HortonWorks distribution and Amazon EMR distribution but failed every time. Please help.
