Subject Re: Can't I mix non-Spark properties into a .properties file and pass it to spark-submit via --properties-file?
Date Mon, 16 Feb 2015 15:41:50 GMT
I haven't actually tried mixing non-Spark settings into the Spark
properties. Instead I package my properties into the jar and use the
Typesafe Config[1] - v1.2.1 - library (along with Ficus[2] - Scala
specific) to get at my properties:

Properties file: src/main/resources/integration.conf

(below $ENV might be set to either "integration" or "prod"[3])

ssh -t root@$HOST "/root/spark/bin/spark-shell --jars /root/$JAR_NAME \
    --conf 'config.resource=$ENV.conf' \
    --conf 'spark.executor.extraJavaOptions=-Dconfig.resource=$ENV.conf'"

Since the properties file is packaged up with the JAR I don't have to worry
about sending the file separately to all of the slave nodes. Typesafe
Config is written in Java so it will work if you're not using Scala. (The
Typesafe Config also has the advantage of being extremely easy to integrate
with code that is using Java Properties today.)

If you instead want to send the file separately from the JAR and you use
the Typesafe Config library, you can specify "config.file" instead of
".resource"; though I'd point you to [3] below if you want to make your
development life easier.
