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: Todd Lipcon 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.
