[jira] Updated: (NUTCH-730) NPE in LinkRank if no nodes with which to create the WebGraph

     [ https://issues.apache.org/jira/browse/NUTCH-730?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Dennis Kubes updated NUTCH-730:
-------------------------------

    Attachment: NUTCH-730-1-20090325.patch

Throws a more detailed error message if there are no nodes to process.  This shouldn't happen on large web graphs but may happen on smaller webgraphs or webgraphs that are all inside one domain (including subdomains).
