[jira] Commented: (HAMA-57) Add the example of Word Count Matrix

["Edward J. Yoon (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HAMA-57?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12631310#action_12631310 ] 

Edward J. Yoon commented on HAMA-57:
------------------------------------

We can collect the <docName1, <<word1, 1>, <word2, 1>, <word2, 1>, ...>> from txt files on hdfs.
Then, using single reduce, we can set the word count matrix as describe below:

  wcmatrix.set(docName1, word1, sumValue);

But, If we would set the integer key ?? we should run the map/reduce job twice for word list.
