齐柏林飞艇不加载马文罐

Question

Apache Zeppelin 版本 0.7.1

%dep
z.reset() // clean up previously added artifact and repository
// add maven repository
z.addRepo("Spark Cassandra Connector 2.0.10").url("https://mvnrepository.com/artifact/com.datastax.spark/spark-cassandra-connector")
// add artifact recursively
// z.load("groupId:artifactId:version")
z.load("com.datastax.spark:spark-cassandra-connector_2.11:2.0.10") 
java.lang.NullPointerException

以下内容似乎没有帮助：

1. 阿帕奇齐柏林飞艇附加存储库导入
2. 在 https://zeppelin.apache.org/docs/0.7.1/interpreter/spark.html 中，它给出了一个将zeppelin.dep.additionalRemoteRepository设置为http://dl.bintray.com/spark-packages/maven的示例，但这个存储库没有我需要的jar版本。
3. https://zeppelin.apache.org/docs/0.7.1/interpreter/spark.html#3-dynamic-dependency-loading-via-sparkdep-interpreter
4. 齐柏林飞艇动态依赖加载在操作系统插件上失败

现在我得到了

%dep
z.load("com.datastax.spark:spark-cassandra-connector_2.11:2.0.10")
org.sonatype.aether.resolution.DependencyResolutionException: Could not find artifact com.datastax.spark:spark-cassandra-connector_2.11:jar:2.0.10 in central (https://repo1.maven.org/maven2/)

Answer 1

我需要将maven 重新定位网址从http更新为httpszeppelin-env.sh

export ZEPPELIN_INTERPRETER_DEP_MVNREPO="https://repo1.maven.org/maven2/"

还有其他特定于我们的构建系统(Jenkins 管道(的非通用更改

如果你可以控制服务器，那么下载你需要的jar会容易得多(即"groupArtifactVersion": "com.datastax.spark:spark-cassandra-connector_2.11:2.0.10",(，然后从磁盘加载依赖项，例如：

%dep
z.load("/opt/zeppelin/spark-cassandra-connector-assembly/spark-cassandra-connector-assembly.jar")
