Comment: was deleted
(was: [~vgrigor] I have created JIRE:SPARK-5479 for support non-local files.
also can you try to run non-local python files on yarn-client mode?
i think that if it is ok, then i can resolve it very quickly. thanks.)
> Python yarn-cluster mode
> ------------------------
>
> Key: SPARK-5162
> URL: https://issues.apache.org/jira/browse/SPARK-5162
> Project: Spark
> Issue Type: New Feature
> Components: PySpark, YARN
> Reporter: Dana Klassen
> Labels: cluster, python, yarn
>
> Running pyspark in yarn is currently limited to ‘yarn-client’ mode. It would
> be great to be able to submit python applications to the cluster and (just
> like java classes) have the resource manager setup an AM on any node in the
> cluster. Does anyone know the issues blocking this feature? I was snooping
> around with enabling python apps:
> Removing the logic stopping python and yarn-cluster from sparkSubmit.scala
> ...
> // The following modes are not supported or applicable
> (clusterManager, deployMode) match {
> ...
> case (_, CLUSTER) if args.isPython =>
> printErrorAndExit("Cluster deploy mode is currently not supported for
> python applications.")
> ...
> }
> …
> and submitting application via:
> HADOOP_CONF_DIR={{insert conf dir}} ./bin/spark-submit --master yarn-cluster
> --num-executors 2 —-py-files {{insert location of egg here}}
> --executor-cores 1 ../tools/canary.py
> Everything looks to run alright, pythonRunner is picked up as main class,
> resources get setup, yarn client gets launched but falls flat on its face:

> transitioned from DOWNLOADING to FAILED
> Tracked this down to the apache hadoop code(FSDownload.java line 249) related
> to container localization of files upon downloading. At this point thought it
> would be best to raise the issue here and get input.
