Subject Re: How to apply data mining on Hive?
Date Fri, 08 Jun 2012 05:25:55 GMT
Hi, Mark.

Thank you for your reply.

I have read the User Guide, but I'm still wondering what can I do for the
following scenario:
----
1. Suppose I have  a table t_customer_info in Hive, which include lots of
information about our customers.
2. Now I would like to cluster those customers into different groups so
that customers within a group have high similarity, but are very dissimilar
to customers in other groups.
3. This is a classical clustering problem in Data Mining field, I thought
such job can not be done by query language, instead of some data mining
algorithms.
----

When we look "back" to the traditional DBMS, there're lots of data mining
tools or BI tools which could connect to the DBMS, and apply some canonical
algorithms to the data in the DBMS. So I start to wonder is there similar
tools over Hive?

If not, what's the most used way to do data mining over Hadoop?
