Andrew Rowson updated HADOOP-11237:
-----------------------------------
Attachment: HADOOP-11237.patch
Patch to simply replace the '=' used in metric names with a '_'.
> GraphiteSink metric names should not contain "="
> ------------------------------------------------
>
> Key: HADOOP-11237
> URL: https://issues.apache.org/jira/browse/HADOOP-11237
> Project: Hadoop Common
> Issue Type: Improvement
> Affects Versions: 2.5.1
> Reporter: Andrew Rowson
> Priority: Minor
> Attachments: HADOOP-11237.patch

>
> GraphiteSink currently outputs an equals character "=" as part of the metric
> key that it outputs to graphite. Graphite doesn't currently support the "="
> as part of a key, and current Graphite trunk breaks when trying to query a
> metric containing this character.
> This can be worked around with wildcarding (carbon appears to store it
> correctly), but it'd be good if metrics sent to graphite used only supported
> characters.
> I propose that we simply use a supported character such as '_'.
