Spark: how to get all configuration parameters

Question

I'm trying to find out what configuration parameters my spark app is executing with. Is there a way to get all parameters, including the default ones?

E.g. if you execute "set;" on a Hive console, it'll list full Hive configuration. I'm looking for an analogous action/command for Spark.

UPDATE: I've tried the solution proposed by karthik manchala. I'm getting these results. As far as I know, these are not all parameters. E.g. this one spark.shuffle.memoryFraction (and a lot more) is missing.

You can do the following:

sparkContext.getConf().getAll();
