Arpit Agarwal updated HDFS-12592:
---------------------------------
Issue Type: Improvement (was: Bug)
> JournalNodeSyncer does not discover newly added JournalNodes
> ------------------------------------------------------------
>
> Key: HDFS-12592
> URL: https://issues.apache.org/jira/browse/HDFS-12592
> Project: Hadoop HDFS
> Issue Type: Improvement
> Reporter: Hanisha Koneru
> Assignee: Hanisha Koneru
>
> The JournalNodeSyncer, during initialization, gets the list of other journal
> nodes from the config. All subsequent sync calls are made to these journal
> nodes. If another journal node is added to the cluster or a journal node is
> restarted at a different address, then the running journalNodeSyncers would
> not be aware of the new/ modified journal nodes.
> We would need to update the shared.edits property in all the journal nodes
> and restart them for the syncers to work correctly.
