Can spark-defaults.conf resolve environment variables? -

-

if have line below in spark-env.sh file

export my_jars==$(jars=(/my/lib/dir/*.jar); ifs=,; echo "${jars[*]}")

which gives me comma delimited list of jars in /my/lib/dir, there way can specify

spark.jars $my_jars

in spark-defaults.conf?

tl;dr no, cannot, there is solution.

spark reads conf file properties file without additional env var substitution.

what write computed value my_jars spark-env.sh straight spark-defaults.conf using >> (append). last wins no worry there many similar entries.
