Subject OutputCollector to print only keys
Date Thu, 08 Jan 2009 12:13:30 GMT
Hi

Does Hadoop 0.18 have an outputcollector that can print out only the
keys and supress the values. In our case we need only the keys, and
hence we do output.collect(key, blank) and then reprocess the entire
output file to remove trailing tabs.

Can this be done more cleanly through the hadoop classes itself.

Many Thanks in Advance
Sandhya
