Subject Reg LZO compression
Date Wed, 17 Oct 2012 02:27:10 GMT
Hi All,

When using lzo compression the file size drastically reduced and the no of
mappers is reduced but the overall execution time is increased, I assume
that because mappers deals with same amount of data.

Is this the expected behavior?
