Shilun Fan updated HDFS-15524: ------------------------------ Affects Version/s: 3.4.0 > Add edit log entry for Snapshot deletion GC thread snapshot deletion > -------------------------------------------------------------------- > > Key: HDFS-15524 > URL: https://issues.apache.org/jira/browse/HDFS-15524 > Project: Hadoop HDFS > Issue Type: Sub-task > Components: snapshots > Affects Versions: 3.4.0 > Reporter: Shashikant Banerjee > Assignee: Shashikant Banerjee > Priority: Major > Fix For: 3.4.0 > > > Currently, Snapshot deletion Gc thread doesn't create an edit log transaction > when the actual snapshot is garbage collected. In cases as such, what might > happen is, if the gc thread deletesĀ snapshots and then namenode is > restarted, snapshots which were garbage collected by the snapshot gc thread > prior restart will reapper till the gc thread again picks them up for garbage > collection as the edits were not captured for actual garbage collection and > at the same time data might have already been deleted from the datanodes > which may lead to too many spurious missing block alerts. -- 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
