Bin:
FYI, there is now a hbase mailing list: See
http://hadoop.apache.org/hbase/mailing_lists.html#Developers. Your
questions (and Ma's on 'connection to HBase using HTable') would sit
better there.

Dear colleagues,
I have a questions on HBase's index implementation.
How does the HBase find the data according to a row key? Use a index
like database, or use a hash function?
I suppose that a hash function which hash row key to physical address
is more efficient.
As we know, a big table in HBase is stored as several Small tables,
each table stores attributes in a column family.
So that, each row may be stored in several small tables.
Does a hash function hash row key to many physical address? Each
physical address correspond to a small table which contains the row
key?
Does anybody have idea on how to create a index on other attribute?
Best,
Bin YANG
