As [SPARK-3190] and #2106 described, VertexRDDs with more than 4 billion elements are counted incorrectly due to integer overflow when summing partition sizes.
And the PR above expected to fix the issue by converting partition sizes to Longs before summing them. But when the number of vertices in specific partition exceed Integer.MAX_VALUE also can repreduce this issue.
The fundamental cause of this problem is the variable “size” is defined as type Int in class VertexPartitionBase.
def size: Int = mask.cardinality()
