   orc support BloomFilter, I fix code in HoodieOrcConfig,  hive use example :
   ```sql
   CREATE TABLE orc_table stored AS ORC 
   TBLPROPERTIES
   ('orc.compress'='ZLIB',
   'orc.create.index'='true',
   "orc.bloom.filter.columns"="pcid",
   'orc.bloom.filter.fpp'='0.05',
   'orc.stripe.size'='10485760',
   'orc.row.index.stride'='10000') 
   AS 
   SELECT CAST(siteid AS INT) AS id, pcid 
   FROM csv_table 
   DISTRIBUTE BY id sort BY id;
   ```
