Subject ompression And Decompression
Date Wed, 14 Nov 2012 11:16:43 GMT

I have some problems with map-reduced jobs.
I am able to compress the output of map-reduced jobs and place it on HDFS but I am not able
to retrieve the data from HDFS ... thats why I need the way to decompress the data ...
Also I want to run map-reduced job on compressed data ...
Is there any way that Hadoop uses internally which decompresses the data, then runs the job
and gives the result but ultimately the data should remain in compressed form on HDFS ...

Thanks & Regards,
Hardeepsingh Saluja.
