-------------------------------------
Summary: Fix `pickRandomVertex` not to fall into infinite loops
for graphs with one vertex
Key: SPARK-14219
URL: https://issues.apache.org/jira/browse/SPARK-14219
Project: Spark
Issue Type: Bug
Components: GraphX
Reporter: Dongjoon Hyun
Currently, `GraphOps.pickRandomVertex()` falls into infinite loops for graphs
having only one vertex. This issue fixes it by modifying the following
termination-checking condition.
{code}
- if (selectedVertices.count > 1) {
+ if (selectedVertices.count > 0) {
{code}
