-----------------------------------
Summary: 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: **env version: Hadoop3.2.1
Reporter: Shiyou xin
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(','));
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 replase DisabledListDelimiterHandler.
