Which would mean that if I want to have my logs to reside in HDFS I will
have to move them using copyFromLocal or some version thereof and then run
Map/Reduce process against them ? Am I right ?

Thanks

HDFS doesn't support appends. There has been discussion of
implementing single-writer appends, but it hasn't reached the top of
anyone's priority list. Some people (me included) aren't thrilled by
the semantics of atomic append in GFS. To me, it seems like atomic
append is basically a poor-man's map/reduce. *smile*
