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, CheJian
