服务器hbase-site.xml配置如下:
<configuration>
<property>
<name>hbase.rootdir</name>
<value>hdfs://localhost:9000/hbase</value>
</property>
<property>
<name>hbase.cluster.distributed</name>
<value>true</value>
</property>
</configuration>
启动成功后通过hbase shell能插入表能操作。http://192.168.163.128:16010/master-status可以正常访问
etc/hosts 配置如下
127.0.0.1 localhost
127.0.1.1 hadoop-virtual-machine
客户端代码
客户端host如下
127.0.1.1 hadoop-virtual-machine
static {
conf = HBaseConfiguration.create();
// 设置Zookeeper,直接设置IP地址
conf.set("hbase.zookeeper.quorum", "192.168.163.128");
conf.set("hbase.zookeeper.property.clientPort", "2181");
}
public static void createTable(String tableName, String[] family) {
Admin admin;
HTableDescriptor table;
TableName t_name = TableName.valueOf(tableName);
Connection connection = null;
try {
connection = ConnectionFactory.createConnection(conf);
admin = connection.getAdmin();
table = new HTableDescriptor(t_name);
for (int i = 0; i < family.length; i++) {
table.addFamily(new HColumnDescriptor(family));
}
if (admin.tableExists(t_name)) {
System.out.println("Table Exists!!");
System.exit(0);
} else {
admin.createTable(table);
System.out.println("Create Table Success!!! Table Name :[ " + tableName + " ]");
}
admin.close();
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
if (null != connection && !connection.isClosed()) {
connection.close();
}
} catch (IOException e) {
e.printStackTrace();
}
}
}
报错如下
