Angad Singh commented on FALCON-510:
------------------------------------
Another required property: frequency (to optimize hraven's graphite storage for
a job based on its granularity instead of a generic). In general, all process
properties being injected will be optimal.
> Inject falcon related properties to job conf
> --------------------------------------------
>
> Key: FALCON-510
> URL: https://issues.apache.org/jira/browse/FALCON-510
> Project: Falcon
> Issue Type: Improvement
> Reporter: Shwetha G S
>
> Currently there is no falcon context injected at MR job level. The job conf
> has at most the oozie workflow / action ID either in the job name or
> sometimes in the job conf.
> Therefore there is no way for a tool like hraven, which relies completely on
> jobconf and job history data, to identify that a particular job maps to a
> particular falcon process or it's instance time, etc. Right now hraven does
> regex-based job name surgery on a best effort basis before emitting metrics
> to graphite
> Request the following feature in falcon:
> Add the following properties to the job conf (for all jobs - be it a pig
> action or an MR action):
> falcon.process.name
> falcon.process.instancetime
> while we're at it, might as well add any other falcon context as a jobconf
> property (like whether it was a rerun or the input/output feeds, cluster,
> validity, any process properties, etc.)
> This will ofcourse inject at the first job level and cannot ensure that any
> child jobs get the properties passed on (unless we can figure out a way to do
> that too).
