The DictionaryFilter does not enabld successful in my machine.

Hi

I have build the parquet-mr with version of 1.9.0 .  hive with version of 2.2.0.

SQL: select * from users where username='nmJNrQwzvZG';
The table of users stored as parquet file. The column of username has encoded by DictionaryWriter.

Some related configuration about parquet.

SET parquet.enable.dictionary=true;
SET hive.optimize.index.filter=true;
SET parquet.filter.index.enabled=true;



When I run the sql in hive with engine of mr. The DictionaryFilter did not work in this case.

Did I missed some important configuration?



Best Regards,
