------------------------------------
Summary: Racing condition in zipWithIndex
Key: SPARK-4433
URL: https://issues.apache.org/jira/browse/SPARK-4433
Project: Spark
Issue Type: Bug
Components: Spark Core
Affects Versions: 1.0.2, 1.1.1, 1.2.0
Reporter: Xiangrui Meng
Assignee: Xiangrui Meng
Spark hangs with the following code:
{code}
sc.parallelize(1 to 10).zipWithIndex.repartition(10).count()
{code}
This is because ZippedWithIndexRDD triggers a job in getPartitions and it cause
a deadlock in DAGScheduler.getPreferredLocs.
