Error in Setup for Basic Map Reduce Program

[Shin Chan <ha...@gmx.com>]

Hello All

 It used to work earlier but today somehow things are not working :)

 I am trying to create one tutorial for simple Mapper , Reducer and Driver class

 Now in eclipse i try to run the Driver class if gives error

 Exception in thread "main" java.lang.NoClassDefFoundError: com/learn/mapreduce/HighOfSymbol

 If i try to run other way by creating jar and then run this

 % hadoop jar learn.jar

 It gives error that Mapper class cannot be found.

 Why it is happening ?

 Did i miss something , all used to work earlier.

Thanks and Regards ,
