Hi communities, Do you have any idea how to get the pairs of all row key combinations w/o repetition on Map/Reduce as describe below?
Input : (MapFile or Hbase Table) <Key1, Value or RowResult> <Key2, Value or RowResult> <Key3, Value or RowResult> <Key4, Value or RowResult> Output : <Key1, Key2> <Key1, Key3> <Key1, Key4> <Key2, Key3> <Key2, Key4> <Key3, Key4> It would be nice if someone can review my pseudo code of traditional CF using cosine similarity. http://wiki.apache.org/hama/TraditionalCollaborativeFiltering Thanks. -- Best regards, Edward J.
