Elek, Marton reopened HADOOP-15339: ----------------------------------- Since the commit we use this change from ozone/hdds and it worked well. This change is required to have a working ozone/hdds webui as the shared code path tags the common jmx beans with generic key/value tags. I reopen this issue and propose to backport it to branch-3.1 to make it easier to use hdds/ozone with older hadoop versions. # It's a small change # Backward compatible # Safe to use (no issue during the last 6 months) # No conflicts for cherry-pick. > Support additional key/value propereties in JMX bean registration > ----------------------------------------------------------------- > > Key: HADOOP-15339 > URL: https://issues.apache.org/jira/browse/HADOOP-15339 > Project: Hadoop Common > Issue Type: Improvement > Components: common > Reporter: Elek, Marton > Assignee: Elek, Marton > Priority: Major > Fix For: 3.2.0 > > Attachments: HADOOP-15339.001.patch, HADOOP-15339.002.patch, > HADOOP-15339.003.patch > > > org.apache.hadoop.metrics2.util.MBeans.register is a utility function to > register objects to the JMX registry with a given name prefix and name. > JMX supports any additional key value pairs which could be part the the > address of the jmx bean. For example: > _java.lang:type=MemoryManager,name=CodeCacheManager_ > Using this method we can query a group of mbeans, for example we can add the > same tag to similar mbeans from namenode and datanode. > This patch adds a small modification to support custom key value pairs and > also introduce a new unit test for MBeans utility which was missing until now. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: common-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-dev-h...@hadoop.apache.org
