java api 操作hbase，创建表出现错误

Mr3-Water 2017-03-14 10:00:49

我用一台虚拟机，搭建一个单节点的Hadoop开发环境，然后在宿主机上写代码，操作HBase，结果出现下面的异常。
有哪位朋友对这块熟悉的，指点一下哈啊哈。

log4j:WARN No appenders could be found for logger (org.apache.hadoop.util.Shell).

log4j:WARN Please initialize the log4j system properly.

你看看自己的ip是不是也是192.168这个网段的，如果是将192.168.2.227添加都windows下C:\Windows\System32\drivers\etc\hosts文件中如果不是最好虚拟机使用桥接方式重新获取ip

而且感觉那个localhost应该改成虚拟机的ip

public class HBaseUtils { static Configuration conf; static { conf = HBaseConfiguration.create(); conf.set("hbase.zookeeper.quorum", "192.168.2.227"); conf.set("hbase.zookeeper.property.clientPort", "2181"); } /** * 创建表 * * @param tableName 表名 * @param family 列簇 * @throws Exception */ public static void createTable(String tableName, String[] family) throws Exception { HBaseAdmin hBaseAdmin = new HBaseAdmin(conf); System.out.println(hBaseAdmin.toString()); HTableDescriptor tableDescriptor = new HTableDescriptor(tableName); for (int i = 0; i < family.length; i++) { tableDescriptor.addFamily(new HColumnDescriptor(family[i])); } if (hBaseAdmin.tableExists(tableName)) { System.out.println("table is exist!"); System.exit(0); } else { hBaseAdmin.createTable(tableDescriptor); System.out.println("create table success!"); } } } 代码结构是这样的

static { conf = HBaseConfiguration.create(); conf.set("hbase.zookeeper.quorum", "192.168.2.227"); conf.set("hbase.zookeeper.property.clientPort", "2181"); // conf.set("hbase.master","master"); // conf.set("hbase.rootdir", "hdfs://master:60000/hbase"); // conf.setBoolean("hbase.cluster.distributed", true); // conf.setInt("hbase.client.scanner.caching", 10000); // conf.set("zookeeper.znode.parent", "/hbase"); // conf.addResource("hbase-site.xml"); // conf.addResource("core-site.xml"); // conf.addResource("hdfs-site.xml"); } 我在这里设置的是虚拟机的IP呢。。而且我把你说的那个文件放到类路径下也是不行的呀。
