Problem running REEF tutorial #18

Open dj-shin opened 9 years ago

dj-shin commented 9 years ago

I've managed to install requirements needed for running HelloREEF, and succeeded in running java -cp lang/java/reef-examples-0.12.0-incubating-SNAPSHOT-shaded.jar org.apache.reef.examples.hello.HelloREEF.

However, even though I've installed Hadoop, running HelloREEFNoClient with in REEF tutorial fails. When I try java -cp lang/java/reef-examples-0.12.0-incubating-SNAPSHOT-shaded.jar org.apache.reef.examples.hello.HelloREEFNoClient, it waits forever in below state.

I wonder what is the reason of this problem.

Running HelloREEFNoClient has nothing to do with Hadoop, because HelloREEFNoClient runtime uses local runtime instead of YARN runtime. In fact, you've actually succeeded in running HelloREEFNoClient. I'm not sure why the client doesn't terminate by itself, but if you enter Ctrl+C and check the REEF_LOCAL_RUNTIME folder then there should be logs of the client-detached HelloREEF job you just ran.
