---------------------------------------
Summary: Streaming job lacks Scala runtime methods
Key: SPARK-17596
URL: https://issues.apache.org/jira/browse/SPARK-17596
Project: Spark
Issue Type: Bug
Components: Streaming
Affects Versions: 2.0.0
Environment: Linux 4.4.20 x86_64 GNU/Linux
openjdk version "1.8.0_102"
Scala 2.11.8
Reporter: Evgeniy Tsvigun
When using -> in Spark Streaming 2.0.0 jobs, or using
spark-streaming-kafka-0-8_2.11 v2.0.0, and submitting it with spark-submit, I
get the following error:
Exception in thread "main" org.apache.spark.SparkException: Job aborted due
to stage failure: Task 0 in stage 72.0 failed 1 times, most recent failure:
Lost task 0.0 in stage 72.0 (TID 37, localhost): java.lang.NoSuchMethodError:
scala.Predef$.ArrowAssoc(Ljava/lang/Object;)Ljava/lang/Object;
This only happens with spark-streaming, using ArrowAssoc in plain non-streaming
Spark jobs works fine.
I put a brief illustration of this phenomenon to a GitHub repo:
https://github.com/utgarda/spark-2-streaming-nosuchmethod-arrowassoc
Putting only provided dependencies to build.sbt
"org.apache.spark" %% "spark-core" % "2.0.0" % "provided",
"org.apache.spark" %% "spark-streaming" % "2.0.0" % "provided"
using -> anywhere in the driver code, packing it with sbt-assembly and
submitting the job results in an error. This isn't a big problem by itself,
using ArrayAssoc can be avoided, but spark-streaming-kafka-0-8_2.11 v2.0.0 has
it somewhere inside, and generates the same error.
Packing with scala-library, can see the class in the jar after packing, but
it's still reported missing in runtime.
