FW:
Following your suggestion, i read the map/reduce packets under hbase. There
are some ideas shown the following:
1 Can i store the index files in hadoop, just like the nutch what to do ?
And may you give me some better solutions?
2 In lucence index searching about hbase columns, can i do index
searching from the index files stored in the hadoop ?
Above as shown, i need do more code modifications for support these functions.
May you borrow your experience? And how to do these ?

Yes, see hbase/mapred package.
I think you can use the lucene.
But, I'm not sure that Right now Hbase is reliable storage system.

Dear edward yoon,
Our company is called Teltel, which website is www.teltel.com. It is a
company based sip protocol for electron consume products. In our application,
we used many cluster projects from kenerl to top applications, such mysql
cluster, lvs and our developed dht network.
For the petabytes requirement, we need make a perfect design for it. So we
look into the hadoop, hbase, lucence projects, etc. We are very interesting in
the hbase , liking the Bigtables based on google file system.
Can the hbase cooperate with lucence? That is, whether or not the family
columns can be indexed by lucuence, and how to using them smoothly?
The following is my informations:

Dear,
I am looking into the hbase project. As shown in hadoop and hbase guide,
i had set up the platform and used the hbase shell usage. But descriped in
Example Of Relational Algebraic Query Command Uses, i could not do these
commands in our testbed liking the following:
Hbase Shell, 0.0.2 version.
Copyright (c) 2007 by udanax, licensed to Apache Software Foundation.
Type 'help;' for usage.
Hbase> Result = Relation.Projection('year','legnth');
Syntax error : Type 'help;' for usage.
Message : Encountered "Result" at line 1, column 2.
Hbase>
If some wrong, waiting for your answers and thanking for your denotion.
thanks
