Colin Patrick McCabe updated HDFS-7722: --------------------------------------- Resolution: Fixed Fix Version/s: 2.7.0 Status: Resolved (was: Patch Available) > 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 > Fix For: 2.7.0 > > Attachments: HDFS-7722.000.patch, HDFS-7722.001.patch, > HDFS-7722.002.patch, HDFS-7722.003.patch, HDFS-7722.004.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)
