-Re: Generating snappy compressed avro files as hadoop map reduce input files
I am not sure to understand the relation between your problem and the way
the temporary data are stored after the map phase.
However, I guess you are looking for a DataFileWriter and its setCodec
PS : A snappy-compressed avro file is not a standard file which has been
compressed afterwards but really a specific file containing compressed
blocks. This principle is similar to the SequenceFile's. Maybe that's what
you mean by different snappy codec?
