Todd Lipcon resolved HDFS-2824. ------------------------------- Resolution: Fixed Fix Version/s: HA branch (HDFS-1623) Hadoop Flags: Reviewed Committed to branch, thanks Aaron! > HA: failover does not succeed if prior NN died just after creating an edit > log segment > -------------------------------------------------------------------------------------- > > Key: HDFS-2824 > URL: https://issues.apache.org/jira/browse/HDFS-2824 > Project: Hadoop HDFS > Issue Type: Sub-task > Components: ha, name-node > Affects Versions: HA branch (HDFS-1623) > Reporter: Todd Lipcon > Assignee: Aaron T. Myers > Fix For: HA branch (HDFS-1623) > > Attachments: HDFS-2824-HDFS-1623.patch, HDFS-2824-HDFS-1623.patch > > > In stress testing failover, I had the following failure: > - NN1 rolls edit logs and starts writing edits_inprogress_1000 > - NN1 crashes before writing the START_LOG_SEGMENT transaction > - NN2 tries to become active, and calls {{recoverUnfinalizedSegment}}. Since > the log file contains no valid transactions, it is marked as corrupt and > renamed with the {{.corrupt}} suffix > - The sanity check in {{openLogsForWrite}} will refuse to open a new > in-progress log at the same txid. Failover does not proceed. -- This message is automatically generated by JIRA.
