> Ganglia metrics can be only sent to the first metric server
> -----------------------------------------------------------
>
> Key: HADOOP-13477
> URL: https://issues.apache.org/jira/browse/HADOOP-13477
> Project: Hadoop Common
> Issue Type: Bug
> Components: metrics
> Affects Versions: 2.6.4, 2.7.2
> Reporter: JerryXin
> Priority: Minor
> Labels: ganglia, metrics
>
> Ganglia metrics can be only sent to the first metric server.
> If I config namenode.sink.ganglia.servers=host1:8649,host2:8649 in hadoop-metrics2.properties,then metrics can only be sent to host1,host2 will never receive them.This means if gmond on host1 is down,metrics will not be collected.
> This happens because GangliaSink parse metric servers use a getString method in SubsetConfiguration,while this method return only the first element in the list.
