> QJM: Sychronize past log segments to JNs that missed them
> ---------------------------------------------------------
>
> Key: HDFS-4025
> URL: https://issues.apache.org/jira/browse/HDFS-4025
> Project: Hadoop HDFS
> Issue Type: Sub-task
> Components: ha
> Affects Versions: QuorumJournalManager (HDFS-3077)
> Reporter: Todd Lipcon
> Assignee: Hanisha Koneru
> Fix For: QuorumJournalManager (HDFS-3077)
>
> Attachments: HDFS-4025.000.patch, HDFS-4025.001.patch,
> HDFS-4025.002.patch, HDFS-4025.003.patch, HDFS-4025.004.patch,
> HDFS-4025.005.patch, HDFS-4025.006.patch, HDFS-4025.007.patch
>
>
> Currently, if a JournalManager crashes and misses some segment of logs, and
> then comes back, it will be re-added as a valid part of the quorum on the
> next log roll. However, it will not have a complete history of log segments
> (i.e any individual JN may have gaps in its transaction history). This
> mirrors the behavior of the NameNode when there are multiple local
> directories specified.
> However, it would be better if a background thread noticed these gaps and
> "filled them in" by grabbing the segments from other JournalNodes. This
> increases the resilience of the system when JournalNodes get reformatted or
> otherwise lose their local disk.
