Changed the default value of dfs.blockreport.initialDelay to be 0 seconds.
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
