-----------------------------------
Summary: Fix SPARK_EXECUTOR_JAVA_OPTS assignment bug
Key: SPARK-43793
URL: https://issues.apache.org/jira/browse/SPARK-43793
Project: Spark
Issue Type: Sub-task
Components: Spark Docker
Affects Versions: 3.5.0
Reporter: Yikun Jiang
env | grep SPARK_JAVA_OPT_ |...
This is susceptible to a few bugs particularly around newlines in values. I see
two ways around it.
ensuring the matching name is at the start, -E '^SPARK_JAVA_OPT_', and running
all the commands with null-terminated input and output: env -0 and -z on the
other commands
or bash variable prefix expansion
for v in "${!SPARK_JAVA_OPT_@}"; do
SPARK_EXECUTOR_JAVA_OPTS+=( "${!v}" )
done
