Colin Patrick McCabe updated HDFS-7960: --------------------------------------- Status: Open (was: Patch Available) > The full block report should prune zombie storages even if they're not empty > ---------------------------------------------------------------------------- > > Key: HDFS-7960 > URL: https://issues.apache.org/jira/browse/HDFS-7960 > Project: Hadoop HDFS > Issue Type: Bug > Affects Versions: 2.6.0 > Reporter: Lei (Eddy) Xu > Assignee: Colin Patrick McCabe > Priority: Critical > Attachments: HDFS-7960.002.patch > > > The full block report should prune zombie storages even if they're not empty. > We have seen cases in production where zombie storages have not been pruned > subsequent to HDFS-7575. This could arise any time the NameNode thinks there > is a block in some old storage which is actually not there. In this case, > the block will not show up in the "new" storage (once old is renamed to new) > and the old storage will linger forever as a zombie, even with the HDFS-7596 > fix applied. This also happens with datanode hotplug, when a drive is > removed. In this case, an entire storage (volume) goes away but the blocks > do not show up in another storage on the same datanode. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
