-------------------------------------
Summary: JournalNodeSyncer does not discover newly added
JournalNodes
Key: HDFS-12592
URL: https://issues.apache.org/jira/browse/HDFS-12592
Project: Hadoop HDFS
Issue Type: Bug
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.
