[jira] [Updated] (HAMA-892) New interface for custom graph partitioner

     [ https://issues.apache.org/jira/browse/HAMA-892?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Edward J. Yoon updated HAMA-892:
--------------------------------

    Description: 
This issue is related with custom graph partitioner HAMA-891 

Since http://svn.apache.org/repos/asf/hama/trunk/core/src/main/java/org/apache/hama/bsp/Partitioner.java is designed for key value pairs, we need to add Vertex Partitioner interface.

Below also need to be changed.
{code}
  /**
   * @return the destination peer name of the given vertex id, determined by the
   *         partitioner.
   */
  public String getDestinationPeerName(V vertexId) {
    return runner.getPeer().getPeerName(
        getPartitioner().getPartition(vertexId, value,
            runner.getPeer().getNumPeers()));
  }
{code}

Since http://svn.apache.org/repos/asf/hama/trunk/core/src/main/java/org/apache/hama/bsp/Partitioner.java is designed for key value pairs, we need to add new Partitioner interface for graph package.

Below also need to be changed.
{code}
  /**
   * @return the destination peer name of the given vertex id, determined by the
   *         partitioner.
   */
  public String getDestinationPeerName(V vertexId) {
    return runner.getPeer().getPeerName(
        getPartitioner().getPartition(vertexId, value,
            runner.getPeer().getNumPeers()));
  }
{code}
