GraphX doc: triangleCount() requirement overstatement?
According to:
https://spark.apache.org/docs/1.2.0/graphx-programming-guide.html#triangle-counting
"Note that TriangleCount requires the edges to be in canonical orientation (srcId < dstId)"
But isn't this overstating the requirement? Isn't the requirement really that IF there are duplicate edges between two vertices, THEN those edges must all be in the same direction (in order for the groupEdges() at the beginning of triangleCount() to produce the intermediate results that triangleCount() expects)?
If so, should I enter a JIRA ticket to clarify the documentation?
Or is it the case that https://issues.apache.org/jira/browse/SPARK-3650 will make it into Spark 1.3 anyway?

We will merge https://issues.apache.org/jira/browse/SPARK-3650 for 1.3.
Thanks for reminding!
