stack commented on HADOOP-3422:
-------------------------------
Thanks for the review Brian.
Unless objection, I'll commit to TRUNK in the next day or so.
Should I commit to branch-0.19 too? I'd like to but its only a 'major' bug,
not critical nor a blocker.
> Ganglia counter metrics are all reported with the metric name "value", so the
> counter values can not be seen

> The JobInProgress class reports all metrics with the name "value". The
> FileMetrics class puts all of the tags into the name when reporting the
> individual values, but the Ganglia Context does not put the tags into the
> name..
> This patch modifies the context to build names for the counter metrics out of
> the tag values. This enables the user to see the indivdual counter values
> with the ganglia web tool, on a per job basis
