Hi guys, If I have a text file of 10 GB and I want to convert it to sequence file using map-reduce and make filesplits of 1 GB each so that 10 mappers work in parallel on it and convert it to Sequence file output. Can I combine these 10 mapper outputs into 1 sequence file of 10 GB size in reduce stage ? Is it possible ? If yes, would it be a very slow operation ?
-thanks JJ
