Reg LZO compression
Manoj Babu 2012-10-17, 02:27
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?

Cheers!
Manoj.
