代码如下
**
//判断表是否存在
public static boolean tableExists(String tableName) throws IOException {
//Hbase配置文件
HBaseConfiguration configuration = new HBaseConfiguration();
configuration.addResource("hbase-site.xml");
configuration.addResource("hdfs-site.xml");
configuration.addResource("core-site.xml");
configuration.set("hbase.zookeeper.quorum","192.168.159.102:2181");
//获取Hbase管理员对象
HBaseAdmin admin = new HBaseAdmin(configuration);
// //执行
boolean tableExist = admin.tableExists(tableName);
admin.close();
return tableExist;
}**
