Andrew Wang commented on HDFS-7374: ----------------------------------- Yea, precisely :) I don't know how realistic this is in an active cluster with lots of failing disks, but it'd fix it for some users at least. > Allow decommissioning of dead DataNodes > --------------------------------------- > > Key: HDFS-7374 > URL: https://issues.apache.org/jira/browse/HDFS-7374 > Project: Hadoop HDFS > Issue Type: Bug > Reporter: Zhe Zhang > Assignee: Zhe Zhang > Attachments: HDFS-7374-001.patch, HDFS-7374-002.patch > > > We have seen the use case of decommissioning DataNodes that are already dead > or unresponsive, and not expected to rejoin the cluster. > The logic introduced by HDFS-6791 will mark those nodes as > {{DECOMMISSION_INPROGRESS}}, with a hope that they can come back and finish > the decommission work. If an upper layer application is monitoring the > decommissioning progress, it will hang forever. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
