[SPARK-4294][Streaming] The same function should have the same realization.
In class TransformedDStream:
require(parents.length > 0, "List of DStreams to transform is empty")
require(parents.map(_.ssc).distinct.size == 1, "Some of the DStreams have
different contexts")
require(parents.map(_.slideDuration).distinct.size == 1,
"Some of the DStreams have different slide durations")
In class UnionDStream:
if (parents.length == 0)
{ throw new IllegalArgumentException("Empty array of parents") }
if (parents.map(_.ssc).distinct.size > 1)
{ throw new IllegalArgumentException("Array of parents have different
StreamingContexts") }
if (parents.map(_.slideDuration).distinct.size > 1)
{ throw new IllegalArgumentException("Array of parents have different slide
times") }
The function is the same, but the realization is not. I think they shoule
be the same.
