Studying Hadoop or MapReduce can be a daunting task if you get your hand dirty at the start.
I followed the schedule as follows :

[list]
[*]Start with very basics of MR with code.google.com/edu/parallel/dsd-tutorial.html code.google.com/edu/parallel/mapreduce-tutorial.html
[/list]
[list]
[*]Then go for the first two lectures in www.cs.washington.edu/education/courses/cse490h/08au/lectures.htm A very good course intro to MapReduce and Hadoop.
[/list]
[list]
[*]Read the seminal paper labs.google.com/papers/mapreduce.html and its improvements in the updated version http://www.cs.washington.edu/education/courses/cse490h/08au/readings/communications200801-dl.pdf
[/list]
[list]
[*]Then go for all the other videos in the U.Washington link given above.
[*]Try youtubing the terms Map reduce and hadoop to find videos by ORielly and Google RoundTable for good overview of the future of Hadoop and MapReduce
[/list]
[list]
[*]Then off to the most important videos - Cloudera Videos www.cloudera.com/resources/?media=Video and Google MiniLecture Series code.google.com/edu/submissions/mapreduce-minilecture/listing.html
