Hi, Unless I am mistaken, the change to using typesafe ConfigFactory has broken some of the system properties we use in spark.
For example: if we have both -Dspark.speculation=true -Dspark.speculation.multiplier=0.95 set, then the spark.speculation property is dropped. The rules of parseProperty actually document this clearly [1] I am not sure what the right fix here would be (other than replacing use of config that is). Any thoughts ? I would vote -1 for 0.9 to be released before this is fixed.
