ASF GitHub Bot commented on HDFS-16645: --------------------------------------- ZanderXu commented on PR #4518: URL: https://github.com/apache/hadoop/pull/4518#issuecomment-1241475601 @xkrogen Thanks for your comment. do you want to remove the redundant in-progress segment? This diff is only fix the exception "Invalid log manifest". If we plan to remove the redundant in-progress segment, we can use JournalNodeSyncer asynchronously to fix it, such as copying the finalized segment from other JNs and replace it. @jojochuang Master, I'm looking forward your ideas, so that we can push this bug forward. > Multi inProgress segments caused "Invalid log manifest" > ------------------------------------------------------- > > Key: HDFS-16645 > URL: https://issues.apache.org/jira/browse/HDFS-16645 > Project: Hadoop HDFS > Issue Type: Bug > Reporter: ZanderXu > Assignee: ZanderXu > Priority: Major > Labels: pull-request-available > Time Spent: 1h 40m > Remaining Estimate: 0h > > JournalNode will have a residual in-progress segment if it is shut down > abnormally.
