-------------------------------------

Thanks @[~damien.claveau] for reporting this and providing a patch! Can you also add a unit
test in TestGraphiteSink?

> According to the Graphite documentation, the data sent must be in the following format:
<metric path> <metric value> <metric timestamp>
> But some tag values that are flattened in the metricpath string sometimes include whitespaces
and violate the carbon/graphite format.
> For example, the dirpath enumeration from the datanode : 
> FSDatasetState.org.apache.hadoop.hdfs.server.datanode.fsdataset.impl.FsDatasetImpl.Context=FSDatasetState.StorageInfo=FSDataset{dirpath='[/data/1/hdfs/data/current,
/data/2/hdfs/data/current]'}.Hostname=worker1.Capacity 78436466688 1491986609
> Currently, none of the aggregators available in the Graphite ecosystem can handle these
malformed metrics. These whitespaces should be replaced by underscores.
> I will be happy to attach a small patch.
