Where does println output go?

[David Thomas <dt...@gmail.com>]

So I'm having this code:

rdd.foreach(p => {
     print(p)
})

Where can I see this output? Currently I'm running my spark program on a
cluster. When I run the jar using sbt run, I see only INFO logs on the
console. Where should I check to see the application sysouts?

[wxhsdp <wx...@gmail.com>]

rdd.foreach(p => {
     print(p)
})

The above closure gets executed on workers, you need to look at the logs of
the workers to see the output.

but if i'm in local mode, where's the logs of local driver, there are no
/logs and /work dirs in /SPARK_HOME which are set in standalone mode.
