-----------------------------------
Issue Type: Bug (was: Improvement)
> Kubernetes app fails if local files are used
> --------------------------------------------
>
> Key: SPARK-22962
> URL: https://issues.apache.org/jira/browse/SPARK-22962
> Project: Spark
> Issue Type: Bug
> Components: Kubernetes
> Affects Versions: 2.3.0
> Reporter: Marcelo Vanzin
>
> If you try to start a Spark app on kubernetes using a local file as the app
> resource, for example, it will fail:
> {code}
> ./bin/spark-submit [[bunch of arguments]] /path/to/local/file.jar
> {code}
> {noformat}
> + /sbin/tini -s -- /bin/sh -c 'SPARK_CLASSPATH="${SPARK_HOME}/jars/*" &&
> env | grep SPARK_JAVA_OPT_ | sed '\''s/[^=]*=\(.*\)/\1/g'
> \'' > /tmp/java_opts.txt && readarray -t SPARK_DRIVER_JAVA_OPTS <
> /tmp/java_opts.txt && if ! [ -z ${SPARK_MOUNTED_CLASSPATH+x}
> ]; then SPARK_CLASSPATH="$SPARK_MOUNTED_CLASSPATH:$SPARK_CLASSPATH"; fi &&
> if ! [ -z ${SPARK_SUBMIT_EXTRA_CLASSPATH+x} ]; then SP
> ARK_CLASSPATH="$SPARK_SUBMIT_EXTRA_CLASSPATH:$SPARK_CLASSPATH"; fi && if
> ! [ -z ${SPARK_MOUNTED_FILES_DIR+x} ]; then cp -R "$SPARK
> _MOUNTED_FILES_DIR/." .; fi && ${JAVA_HOME}/bin/java
> "${SPARK_DRIVER_JAVA_OPTS[@]}" -cp "$SPARK_CLASSPATH" -Xms$SPARK_DRIVER_MEMOR
> Y -Xmx$SPARK_DRIVER_MEMORY
> -Dspark.driver.bindAddress=$SPARK_DRIVER_BIND_ADDRESS $SPARK_DRIVER_CLASS
> $SPARK_DRIVER_ARGS'
> Error: Could not find or load main class com.cloudera.spark.tests.Sleeper
> {noformat}
> Using an http server to provide the app jar solves the problem.
> The k8s backend should either somehow make these files available to the
> cluster or error out with a more user-friendly message if that feature is not
> yet available.
