From: Robert Dyer To: user@hadoop.apache.org Content-Type: text/plain; charset=ISO-8859-1 I am currently using a SequenceFile as input to my MR job (on Hadoop 1.0.3). This works great, as my input is just a bunch of binary blobs. However it seems SequenceFile is only intended to append new data and never update existing entries. Is that correct? If so, would i be better off moving to something like HBase? - Robert
