It looks mostly correct to me. I am not an expert on sequence files, and I have not checked the text against the spec nor have I checked the binary numbers in it to be sure they add up to the correct lengths etc, but it looks good from a first glance. I can see the SEQ tag at the beginning to mark it as a sequence file and the org.apache.hadoop.io.Text as the type for both the keys and the values.
