Subject Re: reading a binary file
Date Mon, 03 Sep 2012 15:08:06 GMT
Hi Mohammad,

SequenceFileInputFormat<http://hadoop.apache.org/mapreduce/docs/r0.21.0/api/org/apache/hadoop/mapreduce/lib/input/SequenceFileInputFormat.html>
requires
the file to be a sequence of key/value stored in binary (i.e., the key is
stored in the file). In my case, the key is implicitly given by the
position of the value within the file.

Thank you,
Francesco
