      Description

      HADOOP-2326 added a new config parameter for the initial block report that gets sent after DataNode registration.
      The default value for this parameter was 60 sec.

      This Jira changes the default to 0 sec - the approriate default for 1 node or small clusters (say less than 50 nodes)
      This Jira also documents the config parameter in hadoop-defaults.xml
