Subject Is the order of collected outputs in the map step preserved til the reduce step?
Date Thu, 10 May 2012 09:36:05 GMT
Hello all,

i am currently working with a set of data which is chronologically 
ordered (every data element has a timestamp and they are monotonically 
increasing). Please correct me, if i am mistaken, but the data should 
"arrive" chronologically ordered at the mapper, right? But is the order 
in which i push values to the output preserved so that the Iterator 
given as a parameter of the reduce-function contains the values also 
chronologically ordered?

Thank you for help in advance!

Best regards,
