Subject [jira] Updated: (HAMA-258) Considering about in/output system
Date Thu, 03 Jun 2010 06:13:24 GMT

     [ https://issues.apache.org/jira/browse/HAMA-258?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Edward J. Yoon updated HAMA-258:
--------------------------------

             Assignee: Edward J. Yoon
        Fix Version/s: 0.3.0
                           (was: 0.2.0)
    Affects Version/s: 0.3.0
                           (was: 0.2.0)

I'm copying and pasting in/output related things from Wiki, and changing the affect fix version
from 0.2 to 0.3 as we discussed on mailing list.

{code}
    // Set input/output format classes
    bsp.setInputFormat(MyInputFormat.class); 
    bsp.setOutputFormat(MyOutputFormat.class); 

    // Like new MR API, set input/output targets with some concrete classes of both InputFormat
    // and OutputFormat. This method provides more flexible ways to specify targets.
    MyInputFormat.addInputPath(bsp, "/data/data1");
    MyOutputFormat.addOutputPath(bsp, "/result/data1");
    
    // or we could have another type of input/output targets as follows:
    // MyDBInputFormat.addInputTable(bsp, "hbase://localhost/WebData");    
    // MyDBOutputFormat.addOutputTable(bsp, "hbase://localhost/OutputTable");
{code}
