## Proposed changes
Issue Number: close #xxx
<!--Describe your changes.-->
fixed an issue where the hive catalog field delimiter is an empty string,
causing it to be core
1、hive build statement
```
CREATE TABLE `hive_q1`(
`id` int,
`name` string)
ROW FORMAT SERDE
'org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe'
WITH SERDEPROPERTIES (
'field.delim'='',
'serialization.format'='')
STORED AS INPUTFORMAT
'org.apache.hadoop.mapred.TextInputFormat'
OUTPUTFORMAT
'org.apache.hadoop.hive.ql.io.HiveIgnoreKeyTextOutputFormat'
LOCATION
'hdfs://HDFSxxxxx/usr/hive/warehouse/hive_q1'
TBLPROPERTIES (
'transient_lastDdlTime'='1715175063')
```
2、problem
`When the field.delim attribute value is an empty string, the be core dumps
because of the separator problem`
3、be stack
```
