Todd Lipcon created HDFS-3884: --------------------------------- Summary: QJM: Journal format() should reset cached values Key: HDFS-3884 URL: https://issues.apache.org/jira/browse/HDFS-3884 Project: Hadoop HDFS Issue Type: Sub-task Affects Versions: QuorumJournalManager (HDFS-3077) Reporter: Todd Lipcon Assignee: Todd Lipcon Fix For: QuorumJournalManager (HDFS-3077) Attachments: hdfs-3884.txt
Simple bug in the JournalNode: it caches certain values (eg accepted epoch) in memory, and the cached values aren't reset when the journal is formatted. So, after a format, further calls to the same Journal will see the old value for accepted epoch, writer epoch, etc, preventing the journal from being re-used until the JN is restarted. -- This message is automatically generated by JIRA.
