Subject [jira] [Created] (FALCON-796) Enable users to triage data processing issues through falcon
Date Fri, 10 Oct 2014 09:41:33 GMT
Srikanth Sundarrajan created FALCON-796:
-------------------------------------------

             Summary: Enable users to triage data processing issues through falcon
                 Key: FALCON-796
                 URL: https://issues.apache.org/jira/browse/FALCON-796
             Project: Falcon
          Issue Type: Improvement
            Reporter: Srikanth Sundarrajan


Falcon has a wealth of information that can help users to triage issues relating to their
pipelines, but this information is not available in a consumable form to the users. Here is
a suggestion to solve for this issue to some extent.

In a typical usage scenario, users may find that their data has not been generated and that
would require them to walk up the dependency tree to identify the root cause. Luckily all
this information is available within Falcon and can be surfaced. 

A mock of how this would look:

*falcon instance -type feed -name FEED-abc -start 2014-10-01T00:00Z -end 2014-10-01T00:00Z
 -triage*
{noformat}
FEED-abc/2014-10-01T00:00Z MISSING
  + PROCESS-def/2014-10-02T04:00Z WAITING
    + FEED-ghi/2014-10-01T00:00Z MISSING
      + PROCESS-mno/2014-10-01T01:30Z  RUNNING
    + FEED-ghi/2014-10-01T01:00Z MISSING
      + PROCESS-mno/2014-10-01T02:30Z  FAILED
    + FEED-ghi/*                 AVAIALBLE
    + FEED-jkl/*                 AVAILABLE
{noformat}

*falcon instance -type feed -name FEED-abc -start 2014-09-01T00:00Z -end 2014-09-01T00:00Z
