DDL语句如下：
CREATE TABLE ods_usage_naga_dsp_filter (
request row<`value` row<DSP_FILTER_LOG row<`date` varchar,placementid
varchar,reqid varchar,source varchar,`time` varchar,`filter`
array<row<filterName varchar,planId varchar>> >>>,
event_ts as to_timestamp(concat(`date`,`time`),'yyyy-MM-ddHH:mm:ss'),
WATERMARK FOR event_ts AS event_ts - interval '60' second
)WITH (
'connector.type' = 'kafka',
'format.fail-on-missing-field'='false',
'connector.version' = 'universal',

'connector.properties.bootstrap.servers'='xx:9092',
'connector.properties.group.id'='xx_test',
'update-mode' = 'append',
'format.type' = 'json'
);
启动程序报错：
