initial block reports

Key: HADOOP-2444
URL: https://issues.apache.org/jira/browse/HADOOP-2444
Project: Hadoop
Issue Type: Improvement
Components: dfs
Reporter: Sanjay Radia
HADOOP-2326 adds a random backoff for the initial block reports. This however
is static config parameter.
It would be useful to have the NN tell the DN how much to backoff (i.e. rather
than a single configuration parameter for the backoff). This would allow the
system to adjust automatically to cluster size - smaller clusters will startup
faster than larger clusters.
