Jim Kellerman commented on HADOOP-1300: --------------------------------------- Why is this bug assigned to me? It doesn't seem relevant to HBase, which is the only code I am working on. > deletion of excess replicas does not take into account 'rack-locality' > ---------------------------------------------------------------------- > > Key: HADOOP-1300 > URL: https://issues.apache.org/jira/browse/HADOOP-1300 > Project: Hadoop > Issue Type: Bug > Components: dfs > Affects Versions: 0.13.0 > Reporter: Koji Noguchi > Assignee: Hairong Kuang > Fix For: 0.14.0 > > Attachments: excessDel.patch, excessDel1.patch > > > One rack went down today, resulting in one missing block/file. > Looking at the log, this block was originally over-replicated. > 3 replicas on one rack and 1 replica on another. > Namenode decided to delete the latter, leaving 3 replicas on the same rack. > It'll be nice if the deletion is also rack-aware. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
