Sun Rui commented on SPARK-10903:
---------------------------------
There are a number of functions defined in SQLContext.R taking a sqlContext
instance as its first argument. Instead of removing the first argument from
these functions, I'd rather we can allow both cases (that is the sqlContext
parameter is passed or not passed) in these functions, for backward
compatibility.
