Yanbo Liang updated SPARK-12044:
--------------------------------
Description:
1, Add "isNaN" to "Column" for SparkR. Column should has three related variable
functions: isNaN, isNull, isNotNull.
2, Replace "DataFrame.isNaN" with "DataFrame.isnan" at SparkR side. Because
DataFrame.isNaN has been deprecated and will be removed at Spark 2.0.
3, Add "isnull" to "DataFrame" for SparkR. DataFrame should has two related
functions: isnan, isnull.
