I am a beginer in Hadoop.
What is the main diffreence between Context and Output in hadoop.
I know in Context write method is used to write the output and in Output collect method is used to put the output ,other than that is there any major difference.
Or where to use Context and where to use Output in hadoop?
Thanks in advance.

JobCon , the OutputCollecto and the Reporter object used for communicate with Map reduce System
