Subject confused about Data/Disk ratio
Date Mon, 21 Jan 2013 06:47:54 GMT
	I use hbase to store Data, and I have an observation, that is,
	When hbase store 1Gb data, hdfs use 10Gb disk space, and when data
is 60Gb, hdfs use 180Gb disk, and when data is about 2Tb, hdfs use 3Tb disk,

	That is, the ratio of data/disk is not a linear one, and why, 

	Could you help me

Thank you
