Hi,
developing a custom receiver up today I used spark version "2.0.0-SNAPSHOT" and
scala version 2.11.7.
With these version all tests work fine.
I have just switching to "2.0.0-preview" as spark version but not I have
following error :
An exception or error caused a run to abort: class
com.fasterxml.jackson.module.scala.ser.ScalaIteratorSerializer overrides final
method
withResolved.(Lcom/fasterxml/jackson/databind/BeanProperty;Lcom/fasterxml/jackson/databind/jsontype/TypeSerializer;Lcom/fasterxml/jackson/databind/JsonSerializer;)Lcom/fasterxml/jackson/databind/ser/std/AsArraySerializerBase;
java.lang.VerifyError: class
com.fasterxml.jackson.module.scala.ser.ScalaIteratorSerializer overrides final

at java.lang.ClassLoader.defineClass1(Native Method)
I see that using 2.0.0-SNAPSHOT the jackson core version is 2.6.5 ... now 2.6.1
with module scala 2.5.3.
Thanks,
Paolo.
