> When multiple partitions are specified out of order (as compared to the order of fields in the create table command), the partitioning on storage is incorrect. Test script (notice that create table or insert into command has city and then state, while the partitioned by clause has state first and then city):
> {code:java}
> DROP TABLE IF EXISTS hudi_table_mlp;
> CREATE TABLE hudi_table_mlp (    ts BIGINT,    id STRING,    rider STRING,    driver STRING,    fare DOUBLE,    city STRING,    state STRING) USING HUDIoptions(    primaryKey ='id',    preCombineField = 'ts',    hoodie.metadata.record.index.enable = 'true')PARTITIONED BY (state, city)location 'file:///tmp/hudi_table_mlp';
> INSERT INTO hudi_table_mlp VALUES (1695159649,'334e26e9-8355-45cc-97c6-c31daf0df330','rider-A','driver-K',19.10,'san_francisco','california');INSERT INTO hudi_table_mlp VALUES (1695091554,'e96c4396-3fad-413a-a942-4cb36106d721','rider-C','driver-M',27.70,'sunnyvale','california');INSERT INTO hudi_table_mlp VALUES (1695332066,'1dced545-862b-4ceb-8b43-d2a568f6616b','rider-E','driver-O',93.50,'austin','texas');INSERT INTO hudi_table_mlp VALUES (1695516137,'e3cf430c-889d-4015-bc98-59bdce1e530c','rider-F','driver-P',34.15,'houston','texas'); {code}
> This creates partition as follows (note that city and state values are swapped):
> !Screenshot 2024-07-06 at 11.34.17 AM.png!
> Now, if i query with state='texas' filter, there are no results:
> {code:java}
> spark-sql> select * from hudi_table_mlp where state='texas';
> 24/07/06 11:30:36 INFO HoodieFileIndex: Using provided predicates to prune number of target table's partitions scanned from 4 to 0
> Time taken: 0.056 seconds {code}
> I have tested this with master, 0.15.0 and 0.14.1, so it's not a recent regression.
