Hello!
I've read Lars George's blog
http://www.larsgeorge.com/2009/05/hbase-mapreduce-101-part-i.html where at the
end of the article, he mentioned "In the next post I will show you how to

Hello!
Perhaps this question occurs all the time. Maybe it should be in the FAQ.
So, what are the options to achieve secondary index on HBase?
And: what is the best option to implement secondary index on Hbase?
Thank you,

Hello!
The property hbase.zookeeper.quorum is taken from hbase-site.xml on
the HBase master machine.
taken from Hbase master hbase-site.xml

Hello!
I've read the HBase architecture from the book
http://hbase.apache.org/book.html#architecture (HBA)
and confronted with HBase definitive guide (HBDG)
http://ofps.oreilly.com/titles/9781449396107/architecture.html
Some questions raised:
1. How many MemStores can have Region?

Hello!
Thank you for your responses. We are going to implement the solution with
storing the metadata information on HBase and the content of the files
into HDFS map files. We'll keep the reference of the map file in the HBase.
Kind regards,

then we obtain the "magic"
number of mappers 2.
We have observed this behavior, by implementing a Driver for the MR job and
setting up the mapred.map.tasks to 40 let's say. Then the number of mappers are
calculated correctly to 32.

Hello!
I have the following scenario:
1. A temporary HBase table with small number of rows (aprox 100)
2. A cluster with 2 machines that I would like to crunch the data contained in
the rows
I would like to create two mappers that will crunch the data from rows.
How can I achieve this?
