Oozie Shell Action's stdout and stderr output

Question

In Oozie site it say 'Shell action's stdout and stderr output are redirected to the Oozie Launcher map-reduce job task STDOUT that runs the shell command'. Can any one tell me where to exactly look at?

Answer 1

Oozie runs the Shell action in a "launcher" (i.e. dummy Mapper) YARN countainer (#00002) under control of the mandatory AppMaster container (#00001)

1. check your Oozie logs for "external ID job_xxxxx_xxxx"
2. connect to the dreadful YARN console
3. search for application_xxxxx_xxxx (yeah, not "job"...)
4. ignore the AM logs link, go straight to the history link; if you are lucky it will redirect you somewhere
5. hack your way to the stdout and stderr links

Good luck.
