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 > Attachments: HDFS-7722.000.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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
