Todd Lipcon reassigned HDFS-2794: --------------------------------- Assignee: Todd Lipcon (was: Aaron T. Myers) > HA: Active NN may purge edit log files before standby NN has a chance to read > them > ---------------------------------------------------------------------------------- > > Key: HDFS-2794 > URL: https://issues.apache.org/jira/browse/HDFS-2794 > Project: Hadoop HDFS > Issue Type: Sub-task > Components: ha, name-node > Affects Versions: HA branch (HDFS-1623) > Reporter: Aaron T. Myers > Assignee: Todd Lipcon > > Given that the active NN is solely responsible for purging finalized edit log > segments, and given that the active NN has no way of knowing when the standby > reads edit logs, it's possible that the standby NN could fail to read all > edits it needs before the active purges the files. -- This message is automatically generated by JIRA.
