> -----------------------------------------------------------------------
>
> Key: HDFS-7722
> URL: https://issues.apache.org/jira/browse/HDFS-7722
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: datanode
> Affects Versions: 2.6.0
> Reporter: Lei (Eddy) Xu
> Assignee: Lei (Eddy) Xu
> Attachments: HDFS-7722.000.patch, HDFS-7722.001.patch
>
>
> When {{DataNode#checkDiskError}} found disk errors, it removes all block
> metadatas from {{FsDatasetImpl}}. However, it does not removed the
> corresponding {{DataStorage}} and {{BlockPoolSliceStorage}}.
> The result is that, we could not directly run {{reconfig}} to hot swap the
> failure disks without changing the configure file.
