使用Ambari下載的hbase-site.xml作爲配置文件運行測試類
@Test
public void test2() {
try {
Configuration conf = HBaseConfiguration.create();
Connection connection = ConnectionFactory.createConnection(conf);
System.out.println("-----------------------1");
Admin admin = connection.getAdmin();
System.out.println("-----------------------2");
System.out.println(admin.tableExists(TableName.valueOf("testtable")));
System.out.println("-----------------------3");
} catch (Exception e) {
e.printStackTrace();
}
}在執行admin.tableExists(TableName.valueOf("testtable"))這一段內容時

寫一個筆記記錄一下各種坑

筆記完成。使用原生Java API連接HBase的問題已經解決。接下來解決spring-data-hadoop的問題

想辦法解決spring-data-hadoop在執行完操作之後總會報一個錯的問題

今日總結
後來spring-data-hadoop的問題也解決掉了。不過解決方法只是使用了什麼手段不讓它執行了而已。反正也不知道它是幹什麼的，所以看不到報錯了不就ok？
開個玩笑，我怎麼回事那麼不負責任的人。其實是在JIRA上找到了問題的提交，可是似乎並沒有解決。
另外，spring-data-hadoop的更新速度對於HBase已經落後了。官方最新版的reference guide中赫然寫着最新版Hbase-client中已經deprecated的接口和各種方法。
另外，臨下班的時候又接到了新的緊急任務。話說也不是那麼緊急……但是氣氛很緊張。各種接口搞得真的很煩躁。
PS：有道雲markdown在字多的時候真的是卡爆了，有沒有什麼適合記錄開發日誌的工具推薦下？
