Question

我正在尝试使用以下代码连接到hbase：

@测试 public void onTrigger（）引发异常{

    TestRunner runner = getTestRunner();
      runner.run();

}

私有TestRunner getTestRunner（）抛出FileNotFoundException，InitializationException {

    final TestRunner runner = TestRunners.newTestRunner(PutAllHBaseAVRO.class);
    runner.setProperty(PutAllHBaseAVRO.TABLE_NAME, "myTable");
    runner.setProperty(PutAllHBaseAVRO.COLUMN_FAMILY, "cf");
    runner.setProperty(PutAllHBaseAVRO.BATCH_SIZE, "10000");

    getHBaseClientService(runner);

    runner.setProperty(PutAllHBaseAVRO.ROW_ID,"Row1");

    // runner.setProperty(PutAllHBaseAVRO.HBASE_CLIENT_SERVICE, hBaseClient);
    runner.setProperty(PutAllHBaseAVRO.ROW_FIELD_REVERSE_STATEGY, "Reverse");
    runner.setProperty(PutAllHBaseAVRO.TS_FIELD_NAME, "dateTimeValue");
    runner.setProperty(PutAllHBaseAVRO.TS_FIELD_FORMAT, "yyyy-MM-dd'T'HH:mm:ssZ");
    return runner;
}

私有HBaseMyClientService getHBaseClientService（最终TestRunner运行器）抛出InitializationException {

    final HBaseMyClientService hBaseClient = new HBase_1_1_2_MyClientService();


    runner.setProperty(HBaseMyClientService.HADOOP_CONF_FILES, "../hbase-site.xml, ../core-site.xml");

    runner.addControllerService("HBaseMyClientService", hBaseClient);

    //runner.setProperty("Kerberos Principal", "myKerberosPrincipal");

    //runner.setProperty("Kerberos Keytab", "/mypath.keytab");

   // runner.setProperty(HBaseMyClientService.ZOOKEEPER_QUORUM, "hbaseClient");

   // runner.enableControllerService(hBaseClient);

    return hBaseClient;

}

并得到一个错误。不明白为什么我有这样的错误：

“ HBase客户端服务”无效，因为需要HBase客户端服务针对“ ../hbase-site.xml、../core-site.xml”验证的“ Hadoop配置文件”无效，因为“ Hadoop配置文件”不是受支持的属性

TestRunner是为处理器创建的，您可以在创建处理器时看到它，并说“ newTestRunner（PutAllHbaseAvro.class）”。当您调用import matplotlib.pyplot as plt distance = [100, 200, 300, 400, 500, 3000] value = [10, 15, 50, 74, 95, 98] plt.barh(range(len(distance)), value, height=0.6) plt.yticks(range(len(distance)), distance) plt.show()时，它正在尝试在处理器上设置该属性，但是您的处理器没有hadoop conf files属性，该服务具有此属性。要在服务上进行设置，您必须拨打其他电话runner.setProperty(name, value)。

从Java应用程序连接到受Kerberos保护的HBase群集
