Harsh J commented on OOZIE-29:
------------------------------
I agree that this would be unnecessary complexity. We can pass on resource
URIs, and that should suffice. Rest should be up to a client to do/build upon.
> Support hadoop job log retrieval through Oozie WS API
> -----------------------------------------------------
>
> Key: OOZIE-29
> URL: https://issues.apache.org/jira/browse/OOZIE-29
> Project: Oozie
> Issue Type: New Feature
> Reporter: Mohammad Kamrul Islam
>
> Users want to utilize Oozie as only entry/gateway to the Grid system.
> Currently they could get the Oozie log related to their jobs. They could also
> access to the corresponding hadoop job details through Oozie UI that redirect
> to the JT UI of that job.
> However, users strongly prefer to get the job log as Oozie WS API response or
> through Oozie CLI for the debugging purpose.
> This JIRA is to discuss the different options (if any) that Hadoop currently
> supports. And subsequent Oozie's action plan.
>
> Questions are:
> 1. Does hadoop provide any API to retrieve the job log?
> 2. Does hadoop provide any API to get the path(s) of hadoop job logs?
> 3. If the answer is no for the above questions:
> a. Is there any alternatives?
> b. Should we create a Hadoop JIRA for asking to support either of the
> options?
> At the same time, we have to make sure the followings:
> 1. Oozie will work as a pass-thru to hadoop.
> 2. Oozie will not store any hadoop log.
> 3. If hadoop restart loss the job log, oozie will return the same message
> that hadoop replies back
> 4. Oozie could retrieve the hadoop job log started by pig.
> Please comment.
