Brian Bockelman updated HADOOP-3422:
------------------------------------
Attachment: ganglia-patch-3422-and-4137.patch
Updated patch: Silly me, Ganglia has no long data type - and I mapped it to
int32, which overflows quickly (especially when reporting bytes transferred!).
This now maps Long to float in Ganglia.
> 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
