Oozie Launcher failed, finishing Hadoop job gracefully
Oozie Launcher ends
When I first tried with this input file, I succeeded on the hadoop in command.
and in Second, also I succeeded.
but in the hadoop with oozie system, Kmeans can't make clusters..
Where is the start point of the error?
I'm really frustrated..
