[jira] [Created] (HADOOP-11237) GraphiteSink metric names should not contain "="

Andrew Rowson created HADOOP-11237:
--------------------------------------

             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 '_'.
