Add block option to random_mapred()
-----------------------------------
Key: HAMA-123
URL: https://issues.apache.org/jira/browse/HAMA-123
Project: Hama
Issue Type: Improvement
Components: implementation
Affects Versions: 0.1.0
Reporter: Edward J. Yoon
Assignee: Edward J. Yoon
Fix For: 0.1.0
I think,... random matrix won't updated. so, it would be nice if we have a
'blocking' option. (from the beginning)
/**
* Generate matrix with random elements using Map/Reduce
*
* @param conf configuration object
* @param m the number of rows.
* @param n the number of columns.
* @param block create the blocked dense matrix if true
* @return an m-by-n matrix with uniformly distributed random elements.
* @throws IOException
*/
public static DenseMatrix random_mapred(HamaConfiguration conf, int m, int n,
boolean block) throws IOException;
