Reynold Xin 84ea287178 [SPARK-10914] UnsafeRow serialization breaks when two machines have different Oops size. ... UnsafeRow contains 3 pieces of information when pointing to some data in memory (an object, a base offset, and length). When the row is serialized with Java/Kryo serialization, the object layout in memory can change if two machines have different pointer width (Oops in JVM). To reproduce, launch Spark using MASTER=local-cluster[2,1,1024] bin/spark-shell --conf "spark.executor.extraJavaOptions=-XX:-UseCompressedOops" And then run the following scala> sql("select 1 xx").collect() Author: Reynold Xin <rxin@databricks.com> Closes #9030 from rxin/SPARK-10914.		2015-10-08 17:25:14 -07:00
