why SequenceFile cannot run without native GZipCodec?

I guess the performance will be bad, but we should still be able to read/write the file. Correct?

Why do we throw an Exception?

java.util.zip.GzipCodec doesn't expose the underlying codec... that's  
critical to do a *reset*. The native  
org.apache.hadoop.io.compress.GzipCodec _does_ expose the 'reset'  
functionality and hence is the only viable option.
