Wei-Chiu Chuang created HDFS-16027:
--------------------------------------
Summary: HDFS-15245 breaks source code compatibility between
3.3.0 and 3.3.1.
Key: HDFS-16027
URL: https://issues.apache.org/jira/browse/HDFS-16027
Project: Hadoop HDFS
Issue Type: Bug
Components: journal-node, ui
Affects Versions: 3.3.1
Reporter: Wei-Chiu Chuang
Assignee: Wei-Chiu Chuang
Ok, this one is on me.
JournalNodeMXBean is a Public, Evolving interface.
But HDFS-15245 was cherrypicked to branch-3.3 which breaks source compatibility
between 3.3.0 and 3.3.1 by adding the following three methods:
{noformat}
/**
* Get host and port of JournalNode.
*
* @return colon separated host and port.
*/
String getHostAndPort();
/**
* Get list of the clusters of JournalNode's journals
* as one JournalNode may support multiple clusters.
*
* @return list of clusters.
*/
List<String> getClusterIds();
/**
* Gets the version of Hadoop.
*
* @return the version of Hadoop.
*/
String getVersion();
{noformat}
