Subject A record version mismatch occured. Expecting v6, found v32
Date Mon, 02 Feb 2009 15:08:22 GMT
Hi,
I tried to use SequenceFileInputFormat, for this I appended "SEQ" as first
bytes of my "binary" files (with hex editor).
but I get this exception:

A record version mismatch occured. Expecting v6, found v32

What could it be? Is it not enough just to add "SEQ" to binary files?
I use Hadoop v.0.19.0 .

Thanks in advance..
