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.
Cheers
Onder
