Spark-HBase - GCP 模板 (3/3) - 缺少库? [英] Spark-HBase - GCP template (3/3) - Missing libraries?

问题描述

我正在尝试在 GCP 上下文中测试 Spark-HBase 连接器并尝试遵循 指令，要求本地打包 连接器，并且在 Dataproc 上提交作业时出现以下错误(在完成 这些步骤).

I'm trying to test the Spark-HBase connector in the GCP context and tried to follow the instructions, which asks to locally package the connector, and I get the following error when submitting the job on Dataproc (after having completed these steps).

命令

(base) gcloud dataproc jobs submit spark --cluster $SPARK_CLUSTER --class com.example.bigtable.spark.shc.BigtableSource --jars target/scala-2.11/cloud-bigtable-dataproc-spark-shc-assembly-0.1.jar --region us-east1 -- $BIGTABLE_TABLE

错误

线程main"中的异常java.lang.NoClassDefFoundError: org/apache/hadoop/hbase/HBaseConfiguration

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/hadoop/hbase/HBaseConfiguration

推荐答案

我找到了一种可行的方法，通过在 build.sbt 中添加以下依赖项 - 感谢 @jccampanero 寻求指导！

I found a working way, by adding following dependencies in build.sbt - thanks @jccampanero for the guidance !

libraryDependencies += "org.apache.hbase" % "hbase-common" % "2.0.2"
libraryDependencies += "org.apache.hbase" % "hbase-mapreduce" % "2.0.2"
