Subject Re: spark.driver.memory is not set (pyspark, 1.1.0)
Date Wed, 01 Oct 2014 16:42:08 GMT
You can't set up the driver memory programatically in client mode. In
that mode, the same JVM is running the driver, so you can't modify
command line options anymore when initializing the SparkContext.

(And you can't really start cluster mode apps that way, so the only
way to set this is through the command line / config files.)
