Oozie Java Action System.out

Question

I have oozie java action. After successfully completition of the job, I can't find System.out.println output in the oozie log. I'm looking at web console "Job Log" screen. I see log output there related to my oozie job but not System.out.println output. How can I configure oozie so that I can see outputs of `System.out.println?

Answer 1

You should override log4j.properties which is inside the hadoop jar file:

-D log4j.configuration=PATH_TO_FILE

(with a spacebar)

For instance:

oozie job -oozie "$oozieServerUrl" -config $ooziePath/coordinator.properties -D log4j.configuration=PATH_TO_FILE -run -verbose

Answer 2

You can find these output inside containers of yarn. Containers location is defined in hadoop conf, you can refer conf if it is difficult to find logs.Each container have 3 files:

• stderr
• stdout
• syslogs So you may find your output in stdout. You may also use web ui at port 8088 to see output on browser.
