> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: namenode
> Affects Versions: 2.6.0
> Reporter: Yi Liu
> Assignee: Yi Liu
>
> Currently there are 3 weights:
> * local
> * same rack
> * off rack
> But if some nodes cache the block, then it's faster if client read block from
> these nodes. So we should have some more weights as following:
> * local
> * cached & same rack
> * same rack
> * cached & off rack
> * off rack
