### Change Logs
query should process listed partitions avoid driver oom due to large number
files in table
### Impact
currently if multiple partition table，would cause oom easy
eg:
CREATE TABLE `hudi_test`.`tmp_hudi_test_1` (
`id` string,
`name` string,
`dt` bigint,
`day` STRING COMMENT '日期分区',
`hour` INT COMMENT '小时分区'
)using hudi
OPTIONS ('hoodie.datasource.write.hive_style_partitioning' 'false',
'hoodie.datasource.meta.sync.enable' 'false',
'hoodie.datasource.hive_sync.enable' 'false')
tblproperties (
'primaryKey' = 'id',
'type' = 'mor',
'preCombineField'='dt',
'hoodie.index.type' = 'BUCKET',
'hoodie.bucket.index.hash.field' = 'id',
'hoodie.bucket.index.num.buckets'=512
)
PARTITIONED BY (`day`,`hour`);
select * from `hudi_test`.`tmp_hudi_test_1` where day='2023-10-17' would
list much filestatus to driver，and driver would oom（such as table with hundreds
billion records in a partition（day='2023-10-17'））
so submit the pr to fix it
