Steve Vaughan created HDFS-16688:
------------------------------------
Summary: Unresolved Hosts during startup are not synced by
JournalNodes
Key: HDFS-16688
URL: https://issues.apache.org/jira/browse/HDFS-16688
Project: Hadoop HDFS
Issue Type: Improvement
Components: journal-node
Environment: Running in Kubernetes using Java 11, with an HA
configuration.
Reporter: Steve Vaughan
During the JournalNode startup, it builds the list of servers in the
JournalNode set, ignoring hostnames that cannot be resolved. In environments
with dynamic IP address allocations this means that the JournalNodeSyncer will
never sync with hosts that aren't resolvable during startup.
