--------------------------------------
Summary: 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
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 '_'.
