> Project: Hadoop Common
> Issue Type: Bug
> Components: metrics
> Affects Versions: 2.7.2, 2.6.4

> 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.
