# Proposed changes
Iceberg external table couldn't read files on hdfs with ha mode enabled.
This pr is to support reading hdfs ha files for Iceberg external tables.
```
mysql> CREATE EXTERNAL TABLE test
-> ( `id` bigint, `data` varchar)
-> engine=iceberg
-> PROPERTIES
-> ('iceberg.hive.metastore.uris' = 'thrift://172.21.16.26:7004',
-> 'iceberg.database' = 'james_db',
-> 'iceberg.table'='james_table',
-> 'iceberg.catalog.type'='HIVE_CATALOG',
-> 'dfs.nameservices'='HDFS8000463',
-> 'dfs.ha.namenodes.HDFS8000463'='nn2,nn1',
-> 'dfs.namenode.rpc-address.HDFS8000463.nn2'='172.21.16.5:4007',
-> 'dfs.namenode.rpc-address.HDFS8000463.nn1'='172.21.16.26:4007',
->
'dfs.client.failover.proxy.provider.HDFS8000463'='org.apache.hadoop.hdfs.server.namenode.ha.ConfiguredFailoverProxyProvider');

mysql> select * from test;
+------+------+
| id | data |
