Peng Cheng created SPARK-7043:
---------------------------------
Summary: KryoSerializer cannot be used with REPL to interpret code
in which case class definition and its shipping are in the same line
Key: SPARK-7043
URL: https://issues.apache.org/jira/browse/SPARK-7043
Project: Spark
Issue Type: Bug
Components: Spark Shell
Affects Versions: 1.3.1
Environment: Ubuntu 14.04, no hadoop
Reporter: Peng Cheng
When deploying Spark-shell with
"spark.serializer=org.apache.spark.serializer.KryoSerializer" option.
Spark-shell cannot execute the following code (in 1 line):
case class Foo(i: Int);val ret = sc.parallelize((1 to 100).map(Foo),
10).collect()
This problem won't exist for either JavaSerializer or code splitted into 2
lines. The only possible explanation is that KryoSerializer is using a
ClassLoader that is not registered as an subsidiary ClassLoader of the one in
REPL.
A "dirty" fix would be just breaking input by semicolon, but its better to fix
the ClassLoader to avoid other liabilities.
