> Avoid slow disks datanode when reading data
> -------------------------------------------
>
> Key: HDFS-17890
> URL: https://issues.apache.org/jira/browse/HDFS-17890
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: hdfs
> Reporter: JunJieZhao
> Priority: Major
> Labels: pull-request-available
>
> During HDFS read operations, replicas on slow disks should be deprioritized
> so that replicas on healthy disks are preferred.
> Currently, slow disk avoidance is not performed at the disk level when
> reading operations return to the block position.
