Jason updated HADOOP-3422:
--------------------------
Attachment: ganglia-patch-3422-qand-4137-1.patch
This patch removes the thread local code and uses StringBuilder instead of
StringBuffer.
The core ganglia pieces are unchanged.
At this point an outstanding issue is that it is not possible to distinguish
the metrics from different jvms.
> Ganglia counter metrics are all reported with the metric name "value", so the
> counter values can not be seen

> Reporter: Jason

> Remaining Estimate: 1h
>
> 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
