使用Ambari下载的hbase-site.xml作为配置文件运行测试类

    @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();        }    }

在执行admin.tableExists(TableName.valueOf("testtable"))这一段内容时
控制台输出

看起来是Zookeeper的连接有什么问题，一直在不停的重连，尝试解决

2017年8月31日10:46:44

修改host文件，发现里面的映射名写错了

2017年8月31日11:02:14

他妈的连上了

2017年8月31日11:22:40

写一个笔记记录一下各种坑

2017年8月31日14:18:57

笔记完成。使用原生Java API连接HBase的问题已经解决。接下来解决spring-data-hadoop的问题

2017年8月31日15:30:31

想办法解决spring-data-hadoop在执行完操作之后总会报一个错的问题

看起来它在释放连接的时候遇到了什么问题

今日总结

后来spring-data-hadoop的问题也解决掉了。不过解决方法只是使用了什么手段不让它执行了而已。反正也不知道它是干什么的，所以看不到报错了不就ok？

开个玩笑，我怎么回事那么不负责任的人。其实是在JIRA上找到了问题的提交，可是似乎并没有解决。

另外，spring-data-hadoop的更新速度对于HBase已经落后了。官方最新版的reference guide中赫然写着最新版Hbase-client中已经deprecated的接口和各种方法。

另外，临下班的时候又接到了新的紧急任务。话说也不是那么紧急……但是气氛很紧张。各种接口搞得真的很烦躁。

PS：有道云markdown在字多的时候真的是卡爆了，有没有什么适合记录开发日志的工具推荐下？
