-------------------------------
Summary: Support configuring DNS record to get list of journal
nodes.
Key: HDFS-16157
URL: https://issues.apache.org/jira/browse/HDFS-16157
Project: Hadoop HDFS
Issue Type: Improvement
Components: journal-node
Reporter: Leon Gao
Assignee: Leon Gao
We can use a DNS round-robin record to configure list of journal nodes, so we
don't have to reconfigure everything journal node hostname is changed. For
example, in some containerized environment the hostname of journal nodes can
change pretty often.
