Subject Sync-marker in uncompressed sequenceFile
Date Mon, 21 Mar 2011 14:40:53 GMT
Hello my fellow Hadoop users/developers,

I'm reading the SequenceFile source code, and there is a checkAndWriteSync()
method that writes a sync marker every so many bytes. I was wondering what's
the use of the sync marker. I know one can use it to designate the end of a
header, but it's also used in the process of writing the uncompressed data.
 I wish I could have figured it out :(

Thank you so much
