Subject some idea about the Data Compression
Date Thu, 20 Jun 2013 06:29:33 GMT
Hi , everyone

I am working on the data compression
1.data compression before the raw data were uploaded into HDFS.
2.data compression while processing in Hadoop to reduce the pressure on IO.

Can anyone give me some ideas on above 2 directions
