Hello,
I have a dataset which is several terabytes in size. I would like to query
this data using hbase (sql). Would I need to setup mapreduce to use hbase?
Currently the data is stored in hdfs and I am using `hdfs -cat ` to get the
data and pipe it into stdin.

Hi there-

I think you might want to start with the Hbase book, and specifically this
entry...

http://hbase.apache.org/book.html#faq.sql

... and then this one...

http://hbase.apache.org/book.html#datamodel

.. then this one.

http://hbase.apache.org/book.html#mapreduce

MapReduce is not required with Hbase, but it is extremely useful.

Thanks for the response.

Can you give me some use cases of hbase and hdfs only? I am
really hesitant to implement MR because for batch jobs we already use
torque.

Hi there-

I think you probably want to start with these links...

http://hadoop.apache.org/hdfs/
http://hadoop.apache.org/mapreduce/
