Subject Re: HBase internal data structure ??
Date Fri, 08 May 2009 03:58:03 GMT
hbase data is only on hdfs and in memory noting is stored or processed on 
local disk unless its in hdfs.
The current 0.19 data format is hadoop MapFile you can look it up in there 
api docs.
0.20 will have a new data file format not MapFile any longer I thank its 
called HFile in hbase trunk
