Re: How to write a matrix multiplication program in C ++ using
Hadoop?
I do not see any code at the link :
https://issues.apache.org/jira/browse/HADOOP-2515
and when I tried to register to login, I got following the error message:
Errors: Your session has timed out
I have found this link at Haoop web site:
http://wiki.apache.org/hadoop/Matrix?highlight=%28matri%29
but it does not solve my problem for three reasons:
1-The code is for shared-memory architecture but I am looking for a code for
multicomputer (commodity cluster) architecture
2- The code generate random numbers for the matrix but I am looking for a
code to read the inputs form text files and write the result to a text file
3- How can I write the code in c++ and run it on Haoop?

Additionally, matrix package code isn't for shared-memory.
Also, If you can put the matrices data from text file to Hbase, you
can use the matrix multiplication map/reduce code.

You can use Hadoop pipes for c++ map/reduce.
Some info available at

Sorry, i closed that issue, And matrix work in progress.
See also http://lucene.apache.org/mahout/
Thanks.
