Jerry Chabot commented on OOZIE-3458:
-------------------------------------
I've decided to use cron jobs to submit workflow jobs since we can no longer
submit coordinator jobs. I sure hope a test case was added to ensure this
scenario passes in future releases!
> Can no longer submit a coordinator job which has oozie.libpath and
> oozie.coord.application.path set

> Key: OOZIE-3458
> URL: https://issues.apache.org/jira/browse/OOZIE-3458
> Project: Oozie
> Issue Type: Bug
> Affects Versions: 5.1.0
> Reporter: Jerry Chabot
> Priority: Critical
>
> This bug is related to https://issues.apache.org/jira/browse/OOZIE-3457. Our
> Production environment is currently running Amazon EMR 5.19. We want to
> upgrade to EMR 5.22. Oozie will be upgraded from 5.0.0 to 5.1.0. Our
> deployment scripts can no longer submit coordinator jobs after upgrading a
> test environment. Here is a sample post from the oozie client.

> Error: E0307 : E0307: Runtime error [App directory [null] does not exist and
> app definition cannot be created because of missing config value
> [oozie.jobs.api.generated.xml]]
> Note, our code specifies oozie.libpath and oozie.coord.application.path. Is
> this no longer allowed?
> I've narrowed down the problem to the checkAndWriteApplicationXMLToHDFS(...)
> method in V1JobsServlet.java. It is related to the new feature for submitting
> embedded XML within the job submission. This method is check whether the
> workflow.xml or coodinator.xml exists in either oozie.wf.application.path,
> oozie.libpath, oozie.coord.application.path or oozie.bundle.application.path.
> First, why is it checking oozie.libpath? That is not an application path.
> Second, it stops looking as soon as findAppPathsWithFileNames() returns a
> value. Which it will always do when oozie.libpath is set even if an xml
> doesn't exist there. It does not continue looking for an xml file in
> oozie.coord.application.path or oozie.bundle.application.path. I realize
> only one application path should be specified. IIMO, its the oozie.libpath
> check that is the problem.
> Third, the logic is inefficient. Here are two lines. Why call the same method
> again with the same params. You already have the result!
> if (!findAppPathsWithFileNames(appPath, "workflow.xml").isEmpty()) {
> appPathsWithFileNames = findAppPathsWithFileNames(appPath, "workflow.xml");
> }
> It is critical that we upgrade to EMR 5.22. However, we are blocked until we
> figure out a way to get the job submitted and completing successfully. Any
> suggested workarounds would be greatly appreciated. But, I am filing this bug
> to get it fixed so an upgraded Oozie will make it into a future EMR release.
