--------------------------------------
Summary: JVM crash from unsafe memory access for Dataset of class
with List[Long]
Key: SPARK-16652
URL: https://issues.apache.org/jira/browse/SPARK-16652
Project: Spark
Issue Type: Bug
Components: Spark Core
Affects Versions: 1.6.2, 1.6.1
Environment: Scala 2.10.<various>
JDK: "Java HotSpot(TM) 64-Bit Server VM (build 25.74-b02, mixed mode)"
MacOs 10.11.2
Reporter: Daniel Barclay
Generating and writing out a {{Dataset}} of a class that has a {{List}} (or at
least if it's {{List\[Long]}}) member and a {{String}} member causes a JVM
crash.
The crash seems to be related to unsafe memory access especially because
earlier code (before I got it reduced to the current bug test case) reported
"{{java.lang.InternalError: a fault occurred in a recent unsafe memory access
operation in compiled Java code}}".
