Question

我想处理spark上的数据并将其插入HBase。我在用 Hbase-Spark（Apache HBase）库（https://mvnrepository.com/artifact/org.apache.hbase/hbase-spark/2.0.0-alpha4）

我收到以下异常，

问题是HBase-Spark-2.0.0-alpha4版本使用了Spark Logging类，而Spark 2.3.1中已弃用该类。

有人可以帮我解决这个问题吗？

注意：我正在使用Spark 2.3.1和HBase 1.2.6.1

我正在使用Spark 2.2.x，但遇到了相同的问题。我忘记了我设法摆脱了以下哪些依赖关系，但是看到配置中缺少哪个依赖关系并尝试添加它。我应该工作。我相信那是火花流：

Answer 2

到目前为止，我可以使用https://mvnrepository.com/artifact/org.apache.hbase.connectors.spark/hbase-spark/1.0.0

上的版本来解决它

<!-- https://mvnrepository.com/artifact/org.apache.hbase.connectors.spark/hbase-spark -->
<dependency>
    <groupId>org.apache.hbase.connectors.spark</groupId>
    <artifactId>hbase-spark</artifactId>
    <version>1.0.0</version>
</dependency>
