             Summary: Cryptic serde error messages in new producer
                 Key: KAFKA-1241
                 URL: https://issues.apache.org/jira/browse/KAFKA-1241
             Project: Kafka
          Issue Type: Bug
          Components: producer 
    Affects Versions: 0.9.0
            Reporter: Neha Narkhede
            Assignee: Jay Kreps
            Priority: Critical


One of the motivations for the new serde format is better error reporting. I 
was running a test on the new mirror maker when I saw this exception -

java.nio.BufferUnderflowException
        at java.nio.Buffer.nextGetIndex(Buffer.java:480)
        at java.nio.HeapByteBuffer.getInt(HeapByteBuffer.java:336)
        at kafka.common.protocol.types.Type$3.read(Type.java:88)
        at kafka.common.protocol.types.Schema.read(Schema.java:50)
        at kafka.common.protocol.types.ArrayOf.read(ArrayOf.java:30)
        at kafka.common.protocol.types.Schema.read(Schema.java:50)

        at kafka.clients.producer.internals.Sender.run(Sender.java:144)
        at kafka.clients.producer.internals.Sender.run(Sender.java:84)
        at java.lang.Thread.run(Thread.java:619)


I was expecting to see a precise error message about the Request type that 
serde failed for. Instead it says Type$3 and no information on which field.
