Sean Owen commented on SPARK-2075:
----------------------------------
[~zsxwing] I don't expect the byte code to be identical when compiled against
different versions of the underlying library, not necessarily. That's not quite
the issue, but rather how these differences change the naming of anonymous
functions. [~sunrui] I don't think that's quite the issue either. The assembly
*is* made from the module JARs. All are published to Maven Central; please
search http://search.maven.org/ .

> Key: SPARK-2075
> URL: https://issues.apache.org/jira/browse/SPARK-2075
> Project: Spark
> Issue Type: Bug
> Components: Build, Spark Core
> Affects Versions: 1.0.0
> Reporter: Paul R. Brown
> Priority: Critical
>
> Running a job built against the Maven dep for 1.0.0 and the hadoop1
> distribution produces:
> {code}
> java.lang.ClassNotFoundException:
> org.apache.spark.rdd.RDD$$anonfun$saveAsTextFile$1
> {code}
> Here's what's in the Maven dep as of 1.0.0:
> {code}
> jar tvf
> ~/.m2/repository/org/apache/spark/spark-core_2.10/1.0.0/spark-core_2.10-1.0.0.jar
> | grep 'rdd/RDD' | grep 'saveAs'
> 1519 Mon May 26 13:57:58 PDT 2014
> org/apache/spark/rdd/RDD$anonfun$saveAsTextFile$1.class
> 1560 Mon May 26 13:57:58 PDT 2014
> org/apache/spark/rdd/RDD$anonfun$saveAsTextFile$2.class
> {code}
> And here's what's in the hadoop1 distribution:
> {code}
> jar tvf spark-assembly-1.0.0-hadoop1.0.4.jar| grep 'rdd/RDD' | grep 'saveAs'
> {code}
> I.e., it's not there. It is in the hadoop2 distribution:
> {code}
> jar tvf spark-assembly-1.0.0-hadoop2.2.0.jar| grep 'rdd/RDD' | grep 'saveAs'
> 1519 Mon May 26 07:29:54 PDT 2014
> org/apache/spark/rdd/RDD$anonfun$saveAsTextFile$1.class
> 1560 Mon May 26 07:29:54 PDT 2014
> org/apache/spark/rdd/RDD$anonfun$saveAsTextFile$2.class
> {code}
