Hello!
I want to know - what's the difference between zipping a file(compressing)
and actually implementing compression algorithms for compressing some sort
of data?
How much difference does it make and which one is preferable.
I want to compress data to be placed in HDFS.
Thanking You,

hello, I want to use standard compression algorithms for data compression.
This would be possible by writing a code supporting map reduce. Also, there
is an utility or a class in hadoop api, that simply zips the data or files
while emitting keys-values pairs. But, How much does it help? It won;t
