> Project: Hadoop

> Components: dfs
> Reporter: Sanjay Radia
> Fix For: 0.17.0
>
>
> 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.
