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.
