Hello,
How did you install your MapR cluster ? I guess you are running Talend on Windows. Did you install the MapR client following this documentation: http://doc.mapr.com/display/MapR/Setting+Up+the+Client#SettingUptheClient-windows-client
If you did, can you please try to execute a
hadoop fs -ls /

in a CMD, on the windows machine.
Regards,
