Michael Stack commented on HDFS-16540: -------------------------------------- Let me do the latter [~dmanning] ... I'll let folks ask for the backport before doing it for branch-3.3. Thanks for finding this one. > Data locality is lost when DataNode pod restarts in kubernetes > --------------------------------------------------------------- > > Key: HDFS-16540 > URL: https://issues.apache.org/jira/browse/HDFS-16540 > Project: Hadoop HDFS > Issue Type: Bug > Components: namenode > Affects Versions: 3.3.2 > Reporter: Huaxiang Sun > Assignee: Huaxiang Sun > Priority: Major > Labels: pull-request-available > Fix For: 3.4.0, 3.3.5 > > Time Spent: 8h 20m > Remaining Estimate: 0h > > We have HBase RegionServer and Hdfs DataNode running in one pod. When the pod > restarts, we found that data locality is lost after we do a major compaction > of hbase regions. After some debugging, we found that upon pod restarts, its > ip changes. In DatanodeManager, maps like networktopology are updated with > the new info. host2DatanodeMap is not updated accordingly. When hdfs client > with the new ip tries to find a local DataNode, it fails. > -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
