[jira] [Commented] (HAMA-635) numberVertices value is inconsistent among tasks

["Yuesheng Hu (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HAMA-635?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13448558#comment-13448558 ] 

Yuesheng Hu commented on HAMA-635:
----------------------------------

Each task sends the number of vertices to others, then sum up the message to get a global numberVertices.
It will fix the problem. But this solution may be inefficient on large cluster.
