Does anybody know how you can write your own custom mapReduce to scan a
table?

Thank you in advance for your response.

Hi,

I am not sure to understand why this question is asked in the dev mailing
list of hive. You will have more answer using common hadoop or hbase
mailing lists.

The answer is that you have to use a custom InputFormat for HBase like
TableInputFormat
http://hbase.apache.org/apidocs/org/apache/hadoop/hbase/mapreduce/TableInputFormat.html

Bertrand

How about using HCatalogue? I heard it's made for that kind of works.
