---------------------------------
Summary: Spark driver hangs on sc.parallelize() if exception is
thrown during serialization
Key: SPARK-4349
URL: https://issues.apache.org/jira/browse/SPARK-4349
Project: Spark
Issue Type: Bug
Components: Spark Core
Affects Versions: 1.1.0
Reporter: Matt Cheah
Fix For: 1.3.0
Executing the following in the Spark Shell will lead to the Spark Shell hanging
after a stack trace is printed. The serializer is set to the Kryo serializer.
{code}
scala> import com.esotericsoftware.kryo.io.Input
import com.esotericsoftware.kryo.io.Input
scala> import com.esotericsoftware.kryo.io.Output
import com.esotericsoftware.kryo.io.Output
scala> class MyKryoSerializable extends
com.esotericsoftware.kryo.KryoSerializable { def write (kryo:
com.esotericsoftware.kryo.Kryo, output: Output) { throw new
com.esotericsoftware.kryo.KryoException; } ; def read (kryo:
com.esotericsoftware.kryo.Kryo, input: Input) { throw new
com.esotericsoftware.kryo.KryoException; } }
defined class MyKryoSerializable
scala> sc.parallelize(Seq(new MyKryoSerializable, new
MyKryoSerializable)).collect
{code}
A stack trace is printed during serialization as expected, but another stack
trace is printed afterwards, indicating that the driver can't recover:
