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();
}
私人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。无法理解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
最佳答案
为处理器创建了TestRunner,您可以在创建处理器时看到它,并说“ newTestRunner(PutAllHbaseAvro.class)”。当您调用runner.setProperty(name, value)
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,您必须拨打另一个电话runner.setProperty(service, name, value)
。
