Hi, I am pretty a newbie and i am following the quick start guide for single node set up on windows using cygwin.
In this step, $ bin/hadoop fs -put conf input I am getting the following errors. I have got no files under /user/EXT0125622/input/conf/capacity-scheduler.xml. That might be a reason for the errors i get but why does hadoop look for such directory as i have not configured anything like that. so supposably, hadoop is making up and looking for such file and directory? Any idea and help is welcome.
