连接hbase报以下错：

代码为：

val zk_quorum = PropertyUtil.getValueByKey("conf/dipc.properties", "zookeeper_hadoop_connection")
  val zk_port = PropertyUtil.getValueByKey("conf/dipc.properties", "zookeeper_hadoop_port")
  val hbase_parent = PropertyUtil.getValueByKey("conf/dipc.properties", "zookeeper_znode_parent")

  val hbaseConf = HBaseConfiguration.create()
  hbaseConf.set("hbase.zookeeper.quorum", zk_quorum) //设置zooKeeper集群地址，也可以通过将hbase-site.xml导入classpath，但是建议在程序里这样设置
  hbaseConf.set("hbase.zookeeper.property.clientPort", zk_port) //设置zookeeper连接端口，默认2181
  hbaseConf.set("zookeeper.znode.parent",hbase_parent)
  hbaseConf.set(TableInputFormat.INPUT_TABLE, tableName)

  private val conn: Connection = ConnectionFactory.createConnection(hbaseConf)
  private val admin: Admin = conn.getAdmin

dipc.properties

#hadoop ZK客户端连接信息
zookeeper_hadoop_connection=zk1:2181,zk2:2181,zk3:2181
zookeeper_hadoop_port=2181
 
#hbase相关配置
zookeeper_znode_parent=/hbase

解决方案：zookeeper.znode.parent的值不是/hbase ，而是/hbase-unsecure，不同的环境，此默认值不一样，CDH是/hbase，HDP是/hbase-unsecure，我们用的是HDP，修改为hbase即可，或者更改代码为/hbase-unsecure
