> Add ability to create block replicas during off-switch reads

> Key: HDFS-2121
> URL: https://issues.apache.org/jira/browse/HDFS-2121
> Project: Hadoop HDFS
> Issue Type: New Feature
> Reporter: Arun C Murthy

> Idea: when a DFSClient reads an off-switch replica, we could tee an extra,
> temporal replica to the local DN if the NN thinks it makes sense.
> Then we could delete the ones which were part of the original 2 on the rack
> to rebalance or just rely on the balancer... all this would ensure better
> spread across the cluster. This would also help with hotspots on datasets.
> Thoughts?
