Subject is implementing WritableComparable and setting Job.setSortComparatorClass(...) redundant?
Date Tue, 20 Mar 2012 06:47:06 GMT
quick question:

i have a key that already implements WritableComparable. this will be the
intermediary key passed from the map to the reducer.

is it necessary to extend RawComparator and set it on
Job.setSortComparatorClass(Class<? extends RawComparator> cls) ?
