首先，我是在selectdb的官方下载的2.1.4，要问我是怎么下载到的，只需要把2.1.3的链接改成2.1.4就可以下载到最新的selectdb2.1.4版本了
1.我先在select里创建了paimon的catalog:
CREATE CATALOG paimon_catalog PROPERTIES (
"type" = "paimon",
"warehouse" = "hdfs://ns/paimon",
"dfs.nameservices" = "ns",
"dfs.ha.namenodes.ns" = "nn1,nn2,nn3",
"dfs.namenode.rpc-address.ns.nn1" = "x.x.x.x:9000",
"dfs.namenode.rpc-address.ns.nn2" = "x.x.x.x:9000",
"dfs.namenode.rpc-address.ns.nn3" = "x.x.x.x:9000",
"dfs.client.failover.proxy.provider.ns" = "org.apache.hadoop.hdfs.server.namenode.ha.ConfiguredFailoverProxyProvider",
"dfs.client.hedged.read.threadpool.size" = "128",
"dfs.client.hedged.read.threshold.millis" = "500",
"hadoop.username" = "root"
);
2.接下来在selectdb的web ui里可以看到这个表格的具体schema信息：

) ENGINE = PAIMON_EXTERNAL_TABLE;
3.接下来我在flink里查询这个表格里的值：（我用的是dinky集成flink查询paimon的数据）
CREATE CATALOG paimon_catalog WITH
(
'type' = 'paimon',
'warehouse' = 'hdfs://ns/paimon'
);
USE CATALOG paimon_catalog;
USE paimon_catalog.dl_ods;
SET 'execution.checkpointing.max-concurrent-checkpoints' = '3';
SET 'table.exec.sink.upsert-materialize' = 'NONE';
SET 'execution.checkpointing.interval' = '10s';
SET 'execution.checkpointing.min-pause' = '10s';
SET 'taskmanager.numberOfTaskSlots' = '1';
select * from ACT_DL;
得到如下信息：（表格是里是有值的）
4.我再返回SELECTDB WEB UI查询该表格，显示所有列的值为NULL, 但数据行却有！
5.此外我在mysql的客户端workbeach访问doris查询该表的值也为NULL，更奇怪的是workbeach里可以做聚集，但selectdb web ui里显示异常错误
