------------------------------------
Summary: NPE with unpersisting memory-only RDD with RDD fetching
from shuffle service enabled
Key: SPARK-38640
URL: https://issues.apache.org/jira/browse/SPARK-38640
Project: Spark
Issue Type: Bug
Components: Spark Core
Affects Versions: 3.2.1
Reporter: Adam Binford
If you have RDD fetching from shuffle service enabled, memory-only cached RDDs
will fail to unpersist.
```
// spark.shuffle.service.fetch.rdd.enabled=true
val df = spark.range(5)
.persist(StorageLevel.MEMORY_ONLY)
df.count()
df.unpersist(true)
```
