kyuubi-beeline cannot fetch kafka source data on flink engine

[jasionzhou]

./bin/kyuubi-beeline -u 'jdbc:kyuubi://127.0.0.1:10009/' -n flink

CREATE TABLE sou (
   emp_id STRING,
   first_name STRING,
   last_name  STRING,
   designation  STRING
) WITH (
    'connector' = 'kafka',
    'topic' = '202411011230_topic_test01',
    'scan.startup.mode' = 'earliest-offset',
    'properties.bootstrap.servers' = '10.xx.xx.xx:9092',
    'format' = 'json'
);

select * from sou;

Querying this flink source table, it keeps loading, and then there is a 60-second timeout exception, why is that?
