Mark Grover updated SPARK-13670:
--------------------------------
Description:
There's a particular snippet in spark-class
[here|https://github.com/apache/spark/blob/master/bin/spark-class#L86] that
runs the spark-launcher code in a subshell.
{code}
# The launcher library will print arguments separated by a NULL character, to
allow arguments with
# characters that would be otherwise interpreted by the shell. Read that in a
while loop, populating
# an array that will be used to exec the final command.
CMD=()
while IFS= read -d '' -r ARG; do
CMD+=("$ARG")
done < <("$RUNNER" -cp "$LAUNCH_CLASSPATH" org.apache.spark.launcher.Main "$@")
{code}
The problem is that the if the launcher Main fails, this code still still
returns success and continues, even though the top level script is marked {{set
-e}}. This is because the launcher.Main is run within a subshell.
