Spark cassandra连接器Java API，找不到符号CassandraRow

Question

I am trying out the spark-cassandra-connector-japi example from here:

https://github.com/datastax/spark-cassandra-connector/blob/master/doc/7_java_api.md

The maven build fails with the following error:

SimpleApp.java:[24,9] cannot find symbol [ERROR] symbol: class CassandraRow [ERROR] location: class SimpleApp

My pom.xml is shown below

<project>
  <groupId>com.example</groupId>
  <artifactId>simple-project</artifactId>
  <modelVersion>4.0.0</modelVersion>
  <name>Simple Project</name>

        <artifactId>cassandra-driver-mapping</artifactId>
        <version>2.1.9</version>
    </dependency>
  </dependencies>
</project>

Where is the class CassandraRow defined? I have gone through the code in package com.datastax.spark.connector.japi.CassandraJavaUtil and it is not defined there. The example asks to only statically import com.datastax.spark.connector.japi for the example to work.

Any pointers would be much appreciated.

Answer 1

you can make it work doing import com.datastax.spark.connector.CassandraRow;

I'm using the same dependencies as you (regardless of the version)

<dependency>
  <groupId>com.datastax.spark</groupId>
  <artifactId>spark-cassandra-connector-java_2.10</artifactId>
  <version>1.5.0-M2</version>
</dependency>
