The codec classname is serialized into a sequence file itself.
You can detect the codec of a SequenceFile, using its Reader:
http://hadoop.apache.org/common/docs/r0.20.2/api/org/apache/hadoop/io/SequenceFile.Reader.html#getCompressionCodec()Or non-programmatically by viewing the header of the file (cat first
hundred bytes or so), and finding the pattern
"org.apache.hadoop.io.compress" in the stream printed.
