Elmer Garduno resolved SPARK-5052.
----------------------------------
Resolution: Not a Problem
> com.google.common.base.Optional binary has a wrong method signatures
> --------------------------------------------------------------------
>
> Key: SPARK-5052
> URL: https://issues.apache.org/jira/browse/SPARK-5052
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 1.2.0
> Reporter: Elmer Garduno
>
> PR https://github.com/apache/spark/pull/1813 shaded Guava jar file and moved Guava classes to package org.spark-project.guava when Spark is built by Maven.
> When a user jar uses the actual com.google.common.base.Optional transform(com.google.common.base.Function); method from Guava, a java.lang.NoSuchMethodError: com.google.common.base.Optional.transform(Lcom/google/common/base/Function;)Lcom/google/common/base/Optional; is thrown.
> The reason seems to be that the Optional class included on spark-assembly-1.2.0-hadoop1.0.4.jar has an incorrect method signature that includes the shaded class as an argument:
> Expected:
> javap -classpath target/scala-2.10/googlegenomics-spark-examples-assembly-1.0.jar com.google.common.base.Optional
> public abstract <V extends java/lang/Object> com.google.common.base.Optional<V> transform(com.google.common.base.Function<? super T, V>);
> Found:
> javap -classpath lib/spark-assembly-1.2.0-hadoop1.0.4.jar com.google.common.base.Optional
> public abstract <V extends java/lang/Object> com.google.common.base.Optional<V> transform(org.spark-project.guava.common.base.Function<? super T, V>);
