# Proposed changes
Issue Number: close #9511
## Problem Summary:
At present, Doris can only access the hadoop cluster with kerberos
authentication enabled by broker. Hope Doris BE itself supports access to a
kerberos-authenticated HDFS rather than broker.
When create hive external table, users only specify some properties when
creating hive table, as follows:
CREATE EXTERNAL TABLE `t_hive` (
`k1` int NOT NULL COMMENT "",
`k2` char(10) NOT NULL COMMENT "",
`k3` datetime NOT NULL COMMENT "",
`k5` varchar(20) NOT NULL COMMENT "",
`k6` double NOT NULL COMMENT ""
) ENGINE=HIVE
COMMENT "HIVE"
PROPERTIES (
'hive.metastore.uris' = 'thrift://192.168.0.1:9083',
'database' = 'hive_db',
'table' = 'hive_table',
'dfs.nameservices'='hacluster',
'dfs.ha.namenodes.hacluster'='3,4',
'dfs.namenode.rpc-address.hacluster.3'='192.168.0.93:8020',
'dfs.namenode.rpc-address.hacluster.4'='172.21.16.11:8020',
'dfs.client.failover.proxy.provider.hacluster'='org.apache.hadoop.hdfs.server.namenode.ha.ConfiguredFailoverProxyProvider',
'dfs.namenode.kerberos.principal'='hadoop/[email protected]'
'hadoop.security.authentication'='kerberos',
'hadoop.kerberos.principal'='[email protected]',
'hadoop.kerberos.keytab'='/path/to/doris_test.keytab'
);
