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

Thanks for quick response.
I agree HBase keeps data on HDFS.
But my question is there must be some data structure at HBase side to
store
data, what's that ?
or it is totally handled by HDFS ??
