Subject Expressions in MapReduce
Date Sat, 11 Jan 2014 18:45:11 GMT
Are we able to do expresions in Mapreduce
Say if i am having a csv file . which has 2 columns.
The user is giving an expresion
col1  + col2 = col3
Are we able to do this?
And when again the user wants col1 - col2 = col4
Can we do it in the same mapreduce (dynamic change of expressions)

*Thanks & Regards*
