1. 参考官方文档-使用2.x及之前的开发指南（https://support.huaweicloud.com/devg-mrs/mrs_06_0187.html），开发指南(适用于2.x及之前)->Spark应用开发章节->Spark on HBase，将样例代码的pom文件hbase.version 配置成<hbase.version>1.3.1-mrs-1.9.0</hbase.version>，样例大妈中对应的CreateTable、TableInputData、TableOutputData类换成如下内容。(其中hbase.zookeeper.quorum值根据不同CloudTable集群会不同，具体的获取联系CloudTableSRE)

CreateTable类如下：

    }

  }

}

 

 

TableOutputData类如下：

        Cell c = it.next();

        String family = Bytes.toString(CellUtil.cloneFamily(c));

        String qualifier = Bytes.toString(CellUtil.cloneQualifier(c));

        String value = Bytes.toString(CellUtil.cloneValue(c));

        Long tm = c.getTimestamp();

        System.out.println(" Family=" + family + " Qualifier=" + qualifier + " Value=" + value + " TimeStamp=" + tm);

      }

    }

    jsc.stop();

  }

}

 

2. 集群的各个节点的/etc/hosts文件添加如下内容（据不同CloudTable集群会不同，具体的获取联系CloudTable服务的SRE）：


3. 找一个1.9.0集群将/opt/client/Spark/spark/jars/下面的这些1.3.1版本的hbase的包

 hbase-client-1.3.1-mrs-1.9.0.jar, hbase-common-1.3.1-mrs-1.9.0.jar, hbase-hadoop2-compat-1.3.1-mrs-1.9.0.jar, hbase-protocol-1.3.1-mrs-1.9.0.jar,  hbase-server-1.3.1-mrs-1.9.0.jar, htrace-core-3.1.0-incubating.jar

都换到3.0.1集群的/opt/client/Spark2x/spark/jars/下面，将/opt/client/Spark2x/spark/jars/下面2.3.2版本的hbase包都移掉。

按照如下步骤执行官方样例代码即可完成：
