Subject [jira] [Commented] (FALCON-510) Inject falcon related properties to job conf
Date Thu, 17 Jul 2014 06:11:04 GMT

    [ https://issues.apache.org/jira/browse/FALCON-510?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14064620#comment-14064620

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.

> 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).
