Zeppelin：运行笔记本时出错

问题描述：

我正在提供我的jar作为依赖关系，以启动Zeppelin的解释器。在运行包含上述jar的服务调用的笔记本时，笔记本保持错误状态。以下异常飞艇日志显示：Zeppelin：运行笔记本时出错

只给约罐子简短的想法，它基本上是阅读和使用星火流写入到卡夫卡。

代码是用Scala编写的，我用Gradle构建了一个Fat-jar。奇怪的是，当我使用SBT构建jar时，它工作正常（使用程序集插件）。这里是我的摇篮文件：

plugins { 
    id "com.github.johnrengelman.shadow" version "1.2.3" 
} 
group 'com.demo' 
version '1.0-SNAPSHOT' 
apply plugin: 'java' 
apply plugin: 'scala' 
sourceCompatibility = 1.8 

configurations { providedCompile } 

repositories { 
    mavenLocal() 
    mavenCentral() 
} 

dependencies { 
    providedCompile group: 'org.apache.spark', name: 'spark-core_2.11', version: '2.0.0' 
    providedCompile group: 'org.apache.spark', name: 'spark-sql_2.11', version: '2.0.0' 
    compile group: 'org.apache.spark', name: 'spark-streaming_2.11', version: '2.0.0' 
    compile group: 'org.apache.spark', name: 'spark-streaming-kafka_2.11', version: '1.6.2' 
    compile group: 'org.apache.spark', name: 'spark-catalyst_2.11', version: '2.0.0' 
    compile group: 'org.apache.kafka', name: 'kafka_2.11', version: '0.9.0.1' 
    compile group: 'org.apache.kafka', name: 'kafka-clients', version: '0.9.0.1' 
    testCompile group: 'junit', name: 'junit', version: '4.11' 
} 



shadowJar { 
    zip64 true 
} 

build.dependsOn(shadowJar); 

sourceSets.main.compileClasspath += configurations.providedCompile 
sourceSets.test.compileClasspath += configurations.providedCompile 
sourceSets.test.runtimeClasspath += configurations.providedCompile

答

这是火花解释依赖性冲突。将以下内容添加到排除项中可能会解决您的问题：

org.scala-lang:scala-library,org.scala-lang:scala-reflect
