Re: Writing MR-Job: Something like OracleReducer, JDBCReducer ...
There is a DBOutputFormat class in the org.apache,hadoop.mapreduce.lib.db
package, you could use that. Or you could write to the hdfs and then use
something like HIHO[1] to export to the db. I have been working extensively
in this area, you can write to me directly if you need any help.
