[SPARK-3190][GraphX] fix VertexRDD.count exceed on large graph
As [SPARK-3190] and https://github.com/apache/spark/pull/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 he number of vertices in specific partition
exceed Integer.MAX_VALUE also can repreduce this issue.
The fundamental cause of this problem is the variable âsizeâ is defined
as type Int in class VertexPartitionBase.
