Lei (Eddy) Xu updated HDFS-7722:
--------------------------------
Attachment: HDFS-7722.000.patch
[~usrikanth] Thanks much for re-assigning this JIRA to me.
This patch makes
* {{FsDatasetImpl#checkDataDirs}} has similar logic as
{{FsDatasetImpl#removeVolumes}}
* {{checkDataDirs()}} returns a set of failed data dirs, so that {{DataNode}}
can call {{DataStorage#removeVolumes}} later to remove metadata associated with
the {{StorageDirectory}}.
> DataNode#checkDiskError should also remove Storage when error is found.

> 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

>
> 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.
