Shiyou xin updated HADOOP-17357:
--------------------------------
Environment: Hadoop3.2.1 (was: **env version: Hadoop3.2.1)
> hadoop component start with failed to init Ganglia31
> ----------------------------------------------------
>
> Key: HADOOP-17357
> URL: https://issues.apache.org/jira/browse/HADOOP-17357
> Project: Hadoop Common
> Issue Type: Bug
> Components: metrics
> Environment: Hadoop3.2.1
> Reporter: Shiyou xin
> Priority: Minor
> Labels: metrics
> Attachments: HADOOP-13660-fix.patch
>
>
> When start namenode, datanode or releated components, there exists an Warning
> :
> Error creating sink 'ganglia'
> org.apache.hadoop.metrics2.impl.MetricsConfigException: Error creating
> plugin: org.apache.hadoop.metrics2.sink.ganglia.GangliaSink31
> if there exists configuration, like :
> *.sink.ganglia.dmax=jvm.metrics.threadsBlocked=70,jvm.metrics.memHeapUsedM=40。
>
> Maybe, because we init first and then configure list delimiter handler。So,
> two ways to deal with this:
> 1. set list delimiter handler first then init parent class:
> (org.apache.hadoop.metrics2.sink.ganglia.GangliaSink30)
> conf.setListDelimiterHandler(new DefaultListDelimiterHandler(','));
> super.init(conf);
> 2. modify related reference jars: commons-configuration2:2.2.1
> org.apache.commons.configuration2.AbstractConfiguration, set default
> delimiter handler replace DisabledListDelimiterHandler.
