I'm thinking to use a SequenceFile as "a little database" to store small files. I need that concurrency-client could store small file in this SequenceFile and retrieve an unique id (key of the record).
Is it possibile ? I'm new to hadoop and I'm reading a lot but I can't figure if it's possibile or not.
If yes, please post a small example (or some reference) if not. What can I do with hadoop for my necessity ?
Well, in the end it's not possible to do what I wanted.
So I switched to HBase and I'm storing files as rows in a table.
Now the performance are ok and all seems to go in the right way.
