While working on upgrading to Spark 1.3.x, notice that the Client and ClientArgument classes in yarn module are now defined as private[spark]. I know that these code are mostly used by spark-submit code; but we call Yarn client directly ( without going through spark-submit) in our spark integration. This change essentially makes us either 1) to fork out the code and un-change the private prefix and build the yarn component ourself or 2) to move the our code to org.apache.spark packages. Currently we are using the #1) approach.
So I am curious to know if there is compelling reason to make these Yarn Client related class private ? Any possibilities make these Client classes non-private ? thanks Chester
